This is strange. I've been profiling gnome-shell 42 on jammy and gnome-
shell 46 on noble. Neither have the bug, at least not with my lowly
1000Hz mice (which seems to be the same polling rate as the Razer
DeathAdder V2).
The profile in comment #18 is intriguing because it very clearly shows
meta_idle_manager_reset_idle_time is the problem for you. But when I
profile my own systems, that function accounts for under 1% of gnome-
shell's time.
Can you think of anything you have like an extension or application
running that might seek to disable screensavers and prevent screen
blanking? A browser or video player maybe?
