Raw Blame History

Unreleased

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)

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Dependency pcre has been replaced by pcre2.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)
