- 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.
|
|
|

Fix the broken -S.
|
|
|
|
|
|
|
| |
- Fix a bug that w->prev_trans sometimes points to freed memory.
Probably related to #165.
- Add some more debugging printf()-s under DEBUG_EVENTS.

- 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)

Add configuration file options for
--unredir-if-possible-{delay,exclude}. (#140)
|
|
|
|

- 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.

Dynamically detect window type as a workaround to insane applications.
Thanks to Feltzer for reporting. (#144)

- 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 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.
|
|
|
|
|
|
|

- Add "redirected_force" to D-Bus opts_get to forcefully
redirect/unredirect windows.
- Add D-Bus method "repaint", to, namely, repaint the screen.

- 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".

- 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.

- 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.

- Fix a bug that ConfigureNotify placing a window in bottom
(ConfigureNotify with .new_above == 0) is not correctly handled,
introduced in 1a88e3d0c5.

- 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.

- 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.
