Fix the bug that --active-opacity state does not change
on `--focus-exclude`-ed windows correctly, since win_update_focused()
enables the WFLAG_OPCT_CHANGE flag on a window only if w->focused
changes, while --active-opacity depends on the output of
win_is_focused_real() instead of w->focused, which could be changed even
if w->focused does not change (e.g. when the window is
`--focus-exclude`-ed).
Always redirect std{out,err} if --logpath is specified, instead of only
redirect after fork, to correct the inconsistent behavior of --logpath
when getppid() returns 1. (#263)
- Add disabled-at-compile-time note in usage text with NO_LIBCONFIG.
- Fix the incorrect disabled-at-compile-time note for --backend.
- Move position of the disabled-at-compile-time note of --dbus
slightly.
- Fix the bug that --no-fading-openclose doesn not work when fading out
by writing w->fade_last as well in win_determine_fade().
- Write w->fade_last for applying w->fade_force, as well.
- Reformat usage text by adding a blank line between descriptions of
two switches. (#215)
- Update documentation for a bit. Correct some wrong statements and
clarify some others.
- Add glx_take_screenshot() for taking a screenshot. With ImageMagick
the output data could be viewed in this way:
display -size [SCREEN-WIDTH]x[SCREEN-HEIGHT] -depth 8 -flip
rgb:[PATH]
(#204)
- Add D-Bus command `opts_get string:paint_on_overlay_id` to get X
Composite overlay window ID. (#204)
- Code cleanup.
- Separate GLX parts from session_t into glx_session_t.
- Add --rererdir-on-root-change and --glx-reinit-on-root-change, as
possible solutions for #217. Thanks to jlindgren90 for reporting.
- Add --glx-fshader-win, which specifies a custom fragment shader for
painting windows. compton-default-fshader-win.glsl is the shader with
default behavior, and compton-fake-transparency-fshader-win.glsl
provides a template of fake transparency. (#183)
- Add --force-win-blend to force all windows to be painted with
blending.
- Add --no-fading-destroyed-argb, as a workaround of bugs in some WMs.
(#193)
Add `bounding_shape` and `rounded_corners` as condition match target.
Deprecate --shadow-ignore-shaped. Add rounded-corners detection to
win_is_fullscreen(). Slightly modify win_rounded_corners() logic. Thanks
to tdryer for reporting. (#191)
- Try to avoid evaluating conditions after window unmap/destruction.
Unfortunately, frequently this doesn't work due to the asynchronous
nature of X.
- Add _GTK_FRAME_EXTENTS exclusion rules to compton.sample.conf. Thanks
to memeplex, hexchain, and others for info. (#189)
- Add debugging option --show-all-xerrors, and other debugging changes.
Doc update.
- Add --xrender-sync{,-fence} to deal with redraw lag issue on GLX
backend. --xrender-sync-fence requires a sufficiently new xorg-server
and libXext. NO_XSYNC=1 may be used to disable it at compile time.
Thanks to tchebb for reporting and everybody else for testing. (#181)
- A bit code clean-up. Replace a few XSync() with XFlush() to minimize
the latency.
- Add "xr-glx-hybrid" as an alias of "xr_glx_hybrid". (#163)
- Clear damage history in expose_root() and when root window size
changes. Unfortunately this doesn't fix#181.
- Add new backend "xr_glx_hybird", which uses X Render for all
compositing but GLX on the last step of rendering to screen. This
makes GLX-backend-specific VSync methods usable while may avoid
certain bugs with GLX backend. The idea comes from ali1234.
Experimental.
- GLX backend: Stop using or rendering to depth buffer.
- Use glFinish() instead of glFlush() before VSync. It probably uses
more CPU but could be more reliable than glFlush().
- Add --write-pid-path to write process ID to a file, to help
determining compton's process ID when -b is used.
- Add a few extra targets to query through D-Bus opts_get (version, pid,
etc.) and through win_get, primarily for debugging.
- Add helper macros likely(), unlikely(), cmalloc(), ccalloc(),
crealloc().
- Change w->opacity_set to opacity_t. Determine display_repr in
session_init(), etc.
Possible fix for a very rare timing issue in focus detection. Compton
may fail to detect the currently focused window, when a window newly
mapped gets focused, we failed to listen to events and get FocusIn from
it in time, and a series of focus change events before it happens stay
in the event queue and puzzled compton. My choice is to force focus
recheck on all focus-related events. More roundtrips to X, but not
necessarily worse performance, due to the high cost of focus flipping
especially when there's a lot of conditions. Thanks to SlackBox for
reporting. (#153)
- Fix a bug that --opacity-rule misbehaves with a value higher than 50%
on 32-bit systems. Thanks to mrinx for reporting. (#149)
- Fix a bug that opacity-rule in configuration file does not work.
- 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.
