- 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.
- inverter.sh: Fix the incorrect rejection of hexadecimal window IDs.
- inverter.sh: Use "invert_color" instead of "invert_color_force" to
determine target window inversion status.
- 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)
