- Add stoppaint_force option, controlled via D-Bus, to stop painting
completely, which may look better than unredirecting the screen,
sometimes. (#41)
- Add x2, y2 matching targets.
- Update documentation.
- Fix OpenGL 3.0 compatibility by changing glFramebufferTexture() to
glFramebufferTexture2D(). Thanks to danfe for suggestion!
- Add notification about DocBook toolchina dependencies. Thanks to
danfe. (#121)
- Add --paint-exclude to prevent certain windows from being painted, for
debugging purposes.
- Add predefined matching target "x", "y", "width", "height", "widthb",
"heightb", "border_width", and "fullscreen".
- Fix bug #119, wrong man page install dir in CMake configuration.
Thanks to sstewartgallus for reporting.
- Add --shadow-exclude-reg, which excludes certain regions on the screen
to have shadows painted in. (#116)
- Adjust session initialization order. Now X root and screen info and
basic X extensions are available in configuration parsing step.
- Add --opacity-rule, which sets opacity based on conditions, as
requested by zabbal. (#113)
- Add a data field for each condition.
- Correct the FAQ link in README.md. Silly me.
- Code clean-up.
- Add multipass blur support. Note GLX Framebuffer support is required.
My benchmark shows multipass blur brings 5% performance boost for X
Render backend (3x3box). On GLX backend it brings 10% performance
boost for 5x5box but negatively affects performance for 3x3box. Thanks
to jrfonseca for advice. (#107)
- GLX backend: Cache blur texture for each window, for a 12% performance
boost.
- Add D-Bus fading control. Thanks to yulan6248 for testing. (#112)
- Fix FAQ link in README.md. Thanks to lorenzos for report. (#111)
- Correctly deinitialize VSync on on-the-fly VSync method switch.
- X Render backend: Normalize blur kernel.
- Code clean-up.
- Known issue: Linear corruption on border of a window may appear with X
Render multi-pass blur. Possible to fix but probably not worthwhile.
- GLX backend: Add DEBUG_GLX_MARK, to add GL marks around functions with
glStringMarkerGREMEDY(), and mark frame termination with
glFrameTerminatorGREMEDY().
- Print output of `compton -h` to stdout. (#110)
- GLX backend: Strip out elements with factor 0 in GLSL blur code.
Thanks to jrfonseca for guides. (#107)
- Fix GL_TEXTURE_RECTANGLE support. Thanks to amonakov for guides.
(#107)
- Enhance --glx-copy-from-front to improve performance and make it work
with --glx-swap-method, copied from kwin patch. Thanks to bwat47 for
info. (#107)
- Add texture2Doffset() support in blur GLSL shader. Thanks to amonakov
for advice. No visible benefit here, though. (#107)
- Only limited tests are done and I'm super sleepy. Bugs expected
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
