Public bug reported:
Xorg sessions on Intel GPUs stutter noticeably in 23.04
Seems like a combination of:
* over-aggressive latency optimizations in the latest version of triple
buffering; and
* gnome-shell 44 being slightly less efficient at some operations like
scrolling the app grid.
Workaround: Add this to /etc/environment:
MUTTER_DEBUG_TRIPLE_BUFFERING=always
** Affects: mutter (Ubuntu)
Importance: Medium
Assignee: Daniel van Vugt (vanvugt)
Status: In Progress
** Tags: lunar performance regression-release triple-buffering
