Richard Grenville a3f6f4442b Improvement: Add predefined blur kernels
- Add a few predefined blur kernels, requested by jerri in #104.

- Add compton-convgen.py to generate blur kernels.
2013-04-29 22:42:46 +08:00
Richard Grenville abd559c512 Bug fix: Fix a BadRegion error with --glx-use-copysubbuffermesa
Just a small and mostly harmless issue. Sorry, didn't test throughly.
2013-04-27 20:43:39 +08:00
Richard Grenville 3f00b3622c Bug fix: Fix --resize-damage
- Fix --resize-damage. I forgot to shrink the painting region back when
  actually copying to destination.

- Include extra pixels around the blur texture to avoid some possible
  small issues, if --resize-damage is positive.

- Known issue: Line artifacts may still appear with --dbe (X Render
  backend) or --glx-swap-method (GLX backend). I doubt if there's way to
  fix this without very inefficient mechanisms.
2013-04-27 17:44:10 +08:00
Richard Grenville 8113e4e3b4 Improvement: --resize-damage
- Add --resize-damage to enlarge/shrink repaint region by a specific
  number of pixels, used for solving the line corruption issue with
  blur. Thanks to Nuck and jerri in #104 for reporting.

- Fix the memory leak of blur shader string.
2013-04-27 11:43:11 +08:00
Richard Grenville c93d8830ff Misc: Fix gcc error

2013-04-26 16:14:37 +08:00
Richard Grenville 5d654e6877 Improvement: Enhance --glx-swap-method
- Enhance --glx-swap-method to support longer buffers ages (3-6), and
  automatic buffer age detection via GLX_EXT_buffer_age.
2013-04-26 14:01:20 +08:00
Richard Grenville 2e6fb0203d Improvement: --blur-kern
- Add blur convolution kernel customization, --blur-kern. The format is
  a bit tricky so be sure to read the description in `compton -h`. Not
  much tests received.

- GLX backend: Tolerate missing GLSL uniforms for strangely shaped
  convolution kernel.

- Fix a memory leak that blur-background blacklist is not freed.
2013-04-25 22:23:35 +08:00
Richard Grenville 4a4f857cc2 Misc: Fix wrong description & DEBUG_GLX_ERR
- Fix description of "opengl" VSync.

- Add DEBUG_GLX_ERR to check for OpenGL errors.

- Update man page.
2013-04-25 09:27:14 +08:00
Richard Grenville 85e7d18803 Improvement: --glx-swap-method & --fade-exclude
- GLX backend: Add --glx-swap-method, to reduce painting region if the
  driver uses exchange or copy buffer swaps. Untested.

- Add --fade-exclude, to disable fading on specific windows based on
  some conditions. Untested.

- Expose GLX backend options through configuration file. Add fetching of
  GLX backend options through D-Bus.

- Use NULL pointer instead of element count to delimit string arrays in
  parse_vsync()/parse_backend()/parse_glx_swap_method().

- Add documentation about "wintypes" section in configuration file.
2013-04-21 22:30:22 +08:00
Richard Grenville a053c0ac64 Bug fix: GLX: Fix dim and blur with --glx-no-stencil
- GLX backend: Fix broken dim and blur with --glx-no-stencil when
  dealing with shaped windows.

- GLX backend: Cache region contents and do a local region intersection
  instead of using XFixesIntersectRegion(). Drastic reduction in CPU
  usage for --glx-no-stencil. Now --glx-no-stencil substantially
  outperforms (~15%) normal mode.

- Use macros to reuse paint-in-region code in opengl.c . Add new type
  "reg_data_t" to store XserverRegion cache.
2013-04-06 20:21:38 +08:00
Richard Grenville e3a15d5f94 Improvement: GLX: Cache region contents & --glx-no-rebind-pixmap
- Cache region contents in is_region_empty(), mostly useful only for GLX
  backend to save one roundtrip to X.

- GLX backend: Add --glx-no-rebind-pixmap, which prevents rebinding of
  GLX texture to pixmap on content change. It doesn't work on some
  drivers, but it saves some CPU on those where it does.

- Wrap XFree() with a new function cxfree() since its man page claims
  NULL pointers are not acceptable (although in fact it does...).

- Use macro to save some code in get_cfg(). Code clean-up.
2013-04-05 21:05:19 +08:00
Richard Grenville 6ef23e066f Misc: Workaround for some missing definitions
- Add workarounds for missing GL_TEXTURE_RECTANGLE and PictOpDifference
  definitions in broken GL headers / old X Composite headers.
2013-04-03 10:53:04 +08:00
Richard Grenville dfd4dd1122 Feature #4: Default active window opacity
- Add default active window opacity (--active-opacity). (#4)

- Add win_focusin and win_focusout D-Bus signals.
2013-03-30 12:27:27 +08:00
Richard Grenville 9e607b2543 Bug fix: GLX: Fix --inactive-dim & fix color inversion
- GLX backend: Fix broken --inactive-dim.

- GLX backend: Fix bugs when inverting colors of windows. Thanks to
  madsy and neure for help.

- GLX backend: Lift `glx_no_stencil` restriction from glx_init_blur().
  It still probably won't work, but the user can try.

- XRender backend: Use XRenderFillRectangles() instead of
  XRenderComposite() to do dimming.
2013-03-25 11:36:39 +08:00
Richard Grenville 75912d23f3 Improvement: --blur-background-exclude #98 & MESA_swap_control & others
- Add --blur-background-exclude. (#98)

- Add `opengl-mswc` VSync, which uses MESA_swap_control instead of
  SGI_swap_control. I don't expect it to perform better than
  SGI_swap_control, though.

- Update CMakeLists.txt .

- Add a few targets for D-Bus `win_get`. Misc changes.

- Known issue: Apparently I've forgotten implementing --inactive-dim on
  GLX backend... Silly me.
2013-03-23 22:06:41 +08:00
Richard Grenville 65cda415dd Bug fix: Incorrect handling when a window is placed on bottom
- Fix a bug that ConfigureNotify placing a window in bottom
  (ConfigureNotify with .new_above == 0) is not correctly handled,
  introduced in 1a88e3d0c5.
2013-03-22 16:44:03 +08:00
Richard Grenville 4b734c1fa1 Improvement: --glx-use-copysubbuffermesa
- GLX backend: Add --glx-use-copysubbuffermesa, to use
  MESA_copy_sub_buffer to do partial screen update. Huge performance
  boost on mesa drivers for partial screen updates, but does not work
  for nvidia-drivers and may break VSync. Automagically overrides
  --glx-copy-from-front.

- Add rect_is_fullscreen() to reuse code. Misc changes.
2013-03-21 13:05:56 +08:00
Richard Grenville 8208ec6dc8 Feature #69: GLX: Blur background
- GLX backend: Add blur background support using a GLSL shader. Only
  tested with nvidia-drivers-313.26. Known to cause quite some decrease
  in performance (~10%?).

- Detach shaders in glx_create_program(). Misc changes.
2013-03-20 17:29:45 +08:00
Richard Grenville 725bc40a65 Improvement: --glx-copy-from-front & benchmark mode
- GLX backend: Add --glx-copy-front, which copies all unmodified regions
  from front buffer to back buffer instead of redrawing the whole
  screen. Unfortunately, probably because glCopyPixels() isn't usually
  well-optimized on graphic cards, this option appears very unstable in
  its effect: Over 20% boost in performance when only 1/4 of the screen
  is modified, but 10% decrease when the whole screen is. Thus, not
  enabled by default.

- GLX backend: Add glx_blur_dst(), to prepare for the background blur
  feature. It currently is capable to modify background in the desired
  way, but the core blur shader is absent. glConvolution2D() seemingly
  relies entirely on CPU and has horrifying performance. I've hesitating
  about whether I should use ARB assembly language or GLSL for the
  shader.

- GLX backend: Invert y-axis GL matrix. It's upside-down previously
  because that's what dcompmgr uses. Seemingly a "normal" y-axis is
  required for glCopyPixels() to operate correctly.

- GLX backend: Fix some GLX_TEXTURE_RECTANGLE compatibility issues.
  Still, not actually tested.

- Add benchmark mode (--benchmark & --benchmark-wid).

- Misc changes.
2013-03-19 20:58:55 +08:00
Richard Grenville a41f05ea92 Improvement: GLX: Use SCISSOR_TEST instead of STENCIL_TEST when possible
- GLX backend: Use GL_SCISSOR_TEST instead of STENCIL_TEST if there's
  only one rectangle in glx_set_clip(). Profiling with gDebugger shows a
  10% performance improvement.

- Add .desktop installation rules. (#97)
2013-03-18 19:01:18 +08:00
Richard Grenville 1a88e3d0c5 Bug fix: GLX: ARGB texture too dark & Jitter when resize & others
- GLX backend: Fix a bug that ARGB windows / shadows are rendered too
  dark. Thanks to derhass in FreeNode/##opengl for help.

- GLX backend: Fix a problem that during window resize the content looks
  jittering, by letting compton fetch pixmap sizes with XGetGeometry()
  instead of relying on window width/height, which could be inaccurate
  during window resize. Negative effect on performance. Thanks to M4he
  for reporting. (#7)

- Add .desktop file. Thanks to quequotion for providing it. (#97)

- Avoid checking presence of window pixmap, because they may not exist
  with very old X Composite implementations.

- Add workaround for a strange window restack issue when compton
  receieves a ConfigureNotify with non-existent new above window.

- Add debugging function hexdump(). Extra sanity checks on various
  places.
2013-03-18 13:29:14 +08:00
Richard Grenville b6a99334ce Bug fix: GLX backend incompatibility with VirtualBox & others
- GLX backend: Fix a bug that window content does not get updated on
  VirtualBox, by rebinding texture when window content changes. This may
  have a negative effect on performance.

- GLX backend: Add --glx-no-stencil to restore the old clipping method,
  just in case.

- GLX backend: Apply stricter checks on texture-pixmap binding.

- GLX backend: Fix a bug that glx_set_clip() behaves incorrectly when
  None is passed in.

- GLX backend: Use glEnable()/glDisable() to toggle stencil tests, in
  hope to increase performance.

- Move window pixmap/picture fetching to win_paint_win(), in hope to
  increase performance.

- Intersect shadow painting region with its bounding rectangle, in hope
  to increase performance.

Richard Grenville 66be1f2fe1 Bug fix: GLX backend incompatibility with mesa & others
- Fix a bug that glx_bind_pixmap() doesn't work with mesa drivers.
  Thanks to Janhouse and mkraemer for reporting. (#7)

- Use stencil buffer to attempt to eliminate potential double-paint
  issue in glx_render(). X Fixes doesn't guarantee the rectangles in a
  region do not overlap, and this may cause some regions to be painted
  twice, which would be a problem if we are painting transparent things.
  Now the target window must have a stencil buffer. Compiz uses its own
  region implementation to deal with this, but as a lightweight
  compositor we can't really do the same. It may have a positive or
  negative effort over performance. Callgrind result indicates basically
  no change in performance, but this may or may not be true.

- Correctly distinguish GL extensions and GLX extensions. Sorry. :-D

- Handle screen size. Thanks to tsmithe for reporting. (#7)

- Rename OpenGL backend to GLX backend, because, we might have a EGL
  backend someday.

- Add configuration file option `backend` to specify backend. Add
  `backend` to D-Bus `opts_get`.

- Add OpenGL shader compilation code, but currently unused.

- Minor adjustments.

- Known issue: Window content doesn't get updated in VirtualBox,
  probably because its OpenGL implementation requires constant rebinding
  of texture. But that's really slow...

- Known issue: Blur feature is still unimplemented in GLX backend.
2013-03-16 22:54:43 +08:00
Richard Grenville 8ffcf1c1e8 Feature: OpenGL backend
- Add experimental OpenGL backend (--opengl). --blur-background is
  currently not possible with this backend, because I'm still trying to
  find a proper way to do blur with OpenGL. Flipping backend on-the-fly
  is really hard, so it isn't supported right now. No configuration file
  option exists to enable this, because it isn't stable enough.

- Add `opengl-swc` VSync method that uses SGI_swap_control to control
  buffer swap, with OpenGL backend. (#7)

- Fix a potential read-from-freed-memory issue in paint_all().

- Correctly reattach GLX context after fork.

- Dump error text in error(). Add GLX error code handling.

- Code clean-up.

- Known issues: Region operations take a lot of time in glx_render().
  I'm hesitating about what to do.
2013-03-15 23:16:23 +08:00
Richard Grenville 4bc3de81ab Bug fix: Create OpenGL context only after initializing overlay
- Create OpenGL context only after initializing overlay, which fixes a
  bug that --paint-on-overlay does not work with OpenGL VSync. Thanks to
  tsmithe for reporting. (#7)
2013-03-12 09:43:14 +08:00
Richard Grenville aace60be59 Improvement: ARGB window matching & Enable track_focus with D-Bus
- Add predefined matching target "argb" to match ARGB windows.

- Make it possible to enable focus tracking on-the-fly with D-Bus
  method.
2013-03-10 18:45:54 +08:00
Richard Grenville b3652f6746 Bug fix #93: Assertion failure when window reparented
- Fix an assertion failure that occurs when a window is reparented to
  the root window then immediately to another window. Thanks to smlx for
  reporting.

- Add extra debugging info for ReparentNotify.
2013-03-03 21:53:08 +08:00
Richard Grenville e3eca7ac61 Bug fix #91: Using pkg-config to find drm.h & OpenGL changes
- #91: Use pkg-config to find drm.h to avoid issues on FreeBSD. Thanks
  to hun7err for pointing out and providing patch.

- #89: Add default shadow exclusion rule for notify-osd. Thanks to
  DanielRS.

- Check for abundant positional arguments.

- Use paint target window (root window / overlay window) instead of
  ps->reg_win to create GLXContext. (May have negative effects on OpenGL
  VSync.) Add new OpenGL helpers functions, to prepare for the new
  OpenGL backend.

- Dump more info of a PropertyNotify with DEBUG_EVENTS.
2013-03-01 12:41:16 +08:00
Richard Grenville 218250546e Misc #86: Compatibility with BSD install
- Make Makefile compatible with BSD install, by dropping -D.

- Make CFG independent in Makefile, to allow people to specify CFLAGS
  as a parameter to make.

- Correct location of .clang_complete.
2013-02-05 16:59:36 +08:00
Richard Grenville 8e34736c19 Improvement: Change VSync mode with D-Bus & Makefile update & Misc
- Add on-the-fly VSync option modification via D-Bus, as requested by
  kunitoki (#80). Expose parse_vsync(), create vsync_init() and
  ensure_glx_context().

- Change default value of ps->drm_fd to -1.

- Update Makefile. Change the install/uninstall rules and add doc
  installation, requested by hasufell in #85.

- Mark window not damaged in map_win(). It helps in reducing flickering
  with inverted window color, but I'm not completely sure if it's safe.

- Avoid modifying w->invert_color when window is unmapped.

- Update documentation. Thanks to hasufell for pointing out.
2013-01-31 22:56:54 +08:00
Richard Grenville 1b5273c819 Improvement #7: Add GLX_OML_sync_control VSync support
- Add "vsync-oml" VSync method, using GLX_OML_sync_control. Untested,
  because it's not supported by my driver.

- Unredirect ps->reg_win, because DRI wiki says it's related to the
  behavior of OpenGL VSync extensions.

- Add glFlush() and glXWaitX() calls, in hope they are slightly helpful
  for VSync.

- Change a few functions to make error handling more graceful. Make some
  errors fatal. Code clean-up.

- Add unused function make_text_prop().
2013-01-30 13:41:08 +08:00
Richard Grenville 42e17cb4e9 Improvement: Improve color inversion performance & Validate pixmap
- Try to improve the performance of color inversion by applying clipping
  region during color inversion. (#75)

- Validate pixmap on window unmap/destruction. Probably slightly helpful
  for #52.

- Change the design of unmap_win() and destroy_win(), a bit.

- Add warning message to help messages about features disabled at
  compile time, instead of dropping their description completely. (#85)

- Silence some warnings. Code clean-up.
