There is heavy stuttering in mutter 45.1/45.2 (especially Firefox)
This is a regression introduced upstream in mutter 45.1, although it only affects the triple buffering patch so that's where it's fixed:

https://gitlab.gnome.org/Community/Ubuntu/mutter/-/commits/triple-buffering-v4-45
[ Workaround ]
In /etc/environment:
MUTTER_DEBUG_TRIPLE_BUFFERING=always
or "never" also works. Just not "auto". |
[ Impact ]
There is heavy stuttering visible in Firefox with mutter 45.1/45.2 when kinetic scrolling a non-animated web page with a touchpad. This is a regression introduced upstream in mutter 45.1 (8f27ebf8).
[ Test Plan ]
0. Find a laptop with a touchpad.
1. Open a simple web page like a Wikipedia page in Firefox.
2. Use two fingers on the touchpad to fling it so it continues scrolling.
Expect: The scrolling proceeds and slows perfectly smoothly.
[ Where problems could occur ]
Anywhere in frame scheduling (visual smoothness), since that is the code affected.
[ Other Info ]
Since the bug only hurts the triple buffering patch, that's where it has been fixed upstream:
