Thanks. And good catch, yes it should be
MUTTER_DEBUG_ENABLE_ATOMIC_KMS=0 on 22.04
It sounds like the main issue is the input rate of the Razer DeathAdder
V2 and gnome-shell's inefficient processing of a high event rate. You
should be able to bring it under control with kernel parameter
usbhid.mousepoll=2 (or 4 or 8). But this is still a gnome-shell
performance bug.
** Summary changed:
- gnome-shell high CPU utilization when moving mouse cursor
+ gnome-shell high CPU utilization when moving a high frequency mouse
** Changed in: gnome-shell (Ubuntu)
Status: Incomplete => New
