Title:
Animations stutter constantly on Nvidia in GNOME 40
Status in Mutter:
Unknown
Status in mutter package in Ubuntu:
Fix Committed
Bug description:
[Impact]
Animations stutter constantly on Nvidia in GNOME 40.
We're missing:
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1826
[Test Plan]
1. Run glxgears and maximize it.
2. Watch closely.
Expect consistently smooth animation.
[Where problems could occur]
Since the fix touches on frame scheduling it could (and should) affect
the smoothness of the entire screen. Although it is designed to only
affect drivers that have `frame_clock->last_presentation_time_us ==
0`, so that's the Nvidia proprietary driver and maybe some virtual
machine configurations.
[Other Info]
The upstream fix mutter!1826 is currently only in mutter 41, not in
the mutter 40 branch yet.
