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
1. Nope, the log is normal, nothing new is logged when moving the cursor
around
2. Razer DeathAdder V2. BTW switching to 60 Hz doesn't seem to change
anything. However, switching to an old cheap mouse decreases gnome-
shell's CPU usage down to ~10%.
3. Unfortunately that didn't help. I also had
Yes it's normal for the application's CPU usage to go up when it's
receiving input events. So that suggests this is just a high frequency
problem.
* Is your log flooding at all? (journalctl -f)
* I can already see you monitor is 144Hz. What model of mouse are you
using?
* Try adding

I'm sorry, the 20% part was a bit of an overstatement, after observing
more I can say it's somewhere between 1% to 5%.
I have the following extensions active:
- Desktop Icons NG
- Ubuntu AppIndicators
- Ubuntu Dock
Disabling all extensions didn't change anything in my case.
Also I've noticed an
20% when idle is 20% too much. So if we find out what that is then the
60% might become 40%.
Do you have any extra gnome-shell extensions active? Can you provide a
photo or screenshot of the desktop?
