picom/CHANGELOG.md

Unreleased

New features

• Allow corner-radius-rules to override corner-radius = 0. Previously setting corner radius to 0 globally disables rounded corners. (#1170)

Notable changes

• Marginally improve performance when resizing/opening/closing windows. (#1190)

v11.2 (2024-Feb-13)

Build changes

• picom now depends on libepoxy 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 (2024-Jan-28)

Bug fixes

• Fix missing fading on window close for some window managers. (#704)

v11 (2024-Jan-20)

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.

v11-rc1 (2024-Jan-14)

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 and GL_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• Dependency pcre has been replaced by pcre2.
• New dependency xcb-util.
• xinerama is no longer used.
• picom now tries to give itself a real-time scheduling priority. Please consider giving picom the CAP_SYS_NICE capability when packaging it.

Deprecations

• The kawase blur method is removed. Note this is just an alias to the dual_kawase method, which is still available. (#1102)
