- Rewrite focus detection logic. Remove w->focused_real and use
ps->active_win to identify focused window uniformly. Use a more
expensive way to filter FocusIn/Out events to improve reliability.
Only limited tests are done, and bugs are likely to be introduced.
(#99)
- Known issue: Under fvwm, compton sometimes does not consistently
report the window input gets sent to. But there's something wrong in
that case: XGetInputFocus() shows the root window is focused but
another window is receiving input.
- Possible fix for high CPU usage with a low --unredir-possible-delay.
Thanks to Feltzer for reporting. (#140)
- Rewrite some parts to (hopefully) increase performance, especially
with --unredir-if-possible.
- Known issue: With GTX 670 and x11-drivers/nvidia-drivers-325.15, and
compton --unredir-if-possible --config /dev/null, if you send a
SIGUSR1 to compton when a full-screen solid window is there, in which
case compton either redirects then immediately unredirects the screen,
or just don't redirect it altogether, X freezes after compton
unredirects the screen. Requests sent by other X clients are not
responded until compton is killed, which indicates the possibility of
a bug in X. Attaching to X process shows X is on ./os/waitFor.c.
Backend does not matter. --paint-on-overlay fixes the issue somehow.
compton-git-v0.1_beta1-5-g4600f43-2013-08-28 doesn't exhibit the
issue, but it's probably timing-related.
- Add --unredir-if-possible-exclude, to exclude certain windows when
evaluating --unredir-if-possible. (#140)
- Add --unredir-if-possible-delay, to add some delay before
unredirecting screen. (#138, #140)
- Code clean-up.
- 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.
