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 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• Dependency pcre has been replaced by pcre2.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)
