Changes since v12-rc2
Bug fixes
transparent-clipping
has no effect (#1317)unredir
in window rules not being parsed correctly- Changing window opacity with
picom-trans

Documentation
- Document behavior change around rounded corners and fullscreen windows
v12-rc2
v12-rc1
Known issues
- Setting
corner-radius
to 0 cause all windows to not render: #1311, fixed by 6b858b8 - Window shaders no longer work: #1312, fixed by fda04bd
New features
-
Animations! Yes, now picom officially supports animations. For examples, and information on how to configure it, please go to our documentation site. There are some video clips in #1253 as well. (#1220 #1253 #1303 #1305 #1308 #1310)
-
Universal window rules (#1284). One option to rule them all! Added new configuration option
rules
to replace all existing rule options, and to provide more flexibility on top of that. See picom(1) for more details. This can be used to configure per-window animations. -
@include
directives in config file now also search in$XDG_CONFIG_HOME/picom/include
and$XDG_CONFIG_DIRS/picom/include
, in addition to relative to the config file's parent directory. -
Allow
corner-radius-rules
to overridecorner-radius = 0
. Previously setting corner radius to 0 globally disables rounded corners. (#1170) -
New
picom-inspect
tool, which lets you test out your picom rules.man picom-inspect(1)
for more details. Sample output:... Checking rounded-corners-exclude: window_type = "dock" ... not matched window_type = "desktop" ... not matched window_type *= "menu" ... not matched fullscreen = 1 ... not matched Checking opacity-rule: _NET_WM_STATE@[0] *= "_NET_WM_STATE_HIDDEN" ... not matched Checking corner-radius-rule: class_g = "Alacritty" ... matched/10 Here are some rule(s) that match this window: name = '[0.2.1] ./picom-inspect: ~/p/picom(./picom-inspect: ~/p/picom)*' class_i = 'Alacritty' class_g = 'Alacritty' window_type = 'normal' ! fullscreen border_width = 0
-
picom now has a rudimentary plugin system. At the moment, the only thing you can do with it is loading custom backends.
Notable changes
override_redirect
in rules now only matches top-level windows that doesn't have a client window. Some window managers (e.g. awesome) set override_redirect for all window manager frame windows, causing this rule to match against everything (#625).- Marginally improve performance when resizing/opening/closing windows. (#1190)
- Type and format specifiers are no longer used in rules. These specifiers are what you put after the colon (':') in rules, e.g. the
:32c
in"_GTK_FRAME_EXTENTS@:32c"
. Now this information is ignored and the property is matched regardless of format or type. backend
is now a required option. picom will not start if one is not specified explicitly.- New predefined target for conditions:
group_focused
. This target indicate whether the focused window is in the same window group as the window being matched. - Meaning of
window_type
in conditions changed slightly, now it supports windows with multiple types. (However the behavior ofwintypes
remains unchanged.)
Deprecated features
- Setting
--shadow-exclude-reg
is now a hard error. It was deprecated almost since the start ofpicom
.--clip-shadow-above
is the better alternative. (#1254) - Remove command line options
-n
,-a
, and-s
. They were removed more than 10 years ago, it's time to finally get rid of them entirely. (#1254) - Remove error message for
--glx-swap-method
, it was deprecated in v6. - Remove error message for passing argument to
--vsync
arguments, it was deprecated in v5. - Option
--opengl
is now deprecated, use--backend=glx
instead.
Bug fixes
- Fix ghosting artifacts that sometimes occur when window manager is restarted (#1081)
- Fix a bug where rounded corner is disabled after making a window fullscreen and back (#1216)
- Fix ugly looking rounded corners (#1261)
Build changes
- picom now uses some OpenGL 4.3 features.
- picom now optionally depends on
rtkit
at runtime to give itself realtime scheduling priority. libconfig
is now a mandatory dependency, with a minimal supported version of 1.7.xcb-dpms
is not needed anymore.libXext
is not needed anymore.- man pages are now built with asciidoctor, instead of asciidoc.
Behind the scene changes
- The X critical section is removed, picom no longer grabs the server to fetch updates. Hopefully, if everything works, this change is unnoticeable. Minor responsiveness improvements could be possible, but I won't bet on it. The main point of this change is this makes debugging much less painful. Previously if you breaks inside the X critical section, the whole X server will lock up, and you would have to connect to the computer remotely to recover. Now there is no longer such worries. This also avoids a bug inside Xorg that makes server grabbing unreliable.
v11.2
Changes since v11.1
Build changes
picom
now depends onlibepoxy
for OpenGL symbol management.
Bug fixes
- Workaround a NVIDIA problem that causes high CPU usage after suspend/resume (#1172, #1168)
- Fix building on OpenBSD (#1189, #1188)
- Fix occasional freezes (#1040, #1145, #1166)
- Fix
corner-radius-rules
not applying sometimes (#1177) - Fix window shader not having an effect when frame opacity is enabled (#1174)
- Fix binding root pixmap in case of depth mismatch (#984)
v11.1
v11
Changes since v11-rc1
Build changes
- Due to some caveats discovered related to setting the
CAP_SYS_NICE
capability, it is now recommended to NOT set this capability for picom.
Deprecations
- Uses of
--sw-opti
, and--respect-prop-shadow
are now hard errors. -F
has been removed completely. It was deprecated before the picom fork.

Changelog
Notable features
- picom now uses dithering to prevent banding. Banding is most notable when using a strong background blur. (#952)
- Frame pacing. picom uses present feedback information to schedule new frames when it makes sense to do so. This improves latency, and replaces the
glFlush
andGL_MaxFramesAllowed=1
hacks we used to do for NVIDIA. (#968 #1156) - Some missing features have been implemented for the EGL backend (#1004 #1007)
Bug fixes
- Many memory/resource leak fixes thanks to @absolutelynothelix . (#977 #978 #979 #980 #982 #985 #992 #1009 #1022)
- Fix tiling of wallpaper. (#1002)
- Fix some blur artifacts (#1095)
- Fix shadow color for transparent shadows (#1124)
- Don't spam logs when another compositor is running (#1104)
- Fix rounded corners showing as black with the xrender backend (#1003)
- Fix blur with rounded windows (#950)
Build changes
- Dependency
pcre
has been replaced bypcre2
. - New dependency
xcb-util
. xinerama
is no longer used.picom
now tries to give itself a real-time scheduling priority.Please consider givingpicom
theCAP_SYS_NICE
capability when packaging it.
Deprecations
- The
kawase
blur method is removed. Note this is just an alias to thedual_kawase
method, which is still available. (#1102)
