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 ] The bug was introduced upstream in 45.1 by https://gitlab.gnome.org/GNOME/mutter/-/commit/8f27ebf87eee6057992a90560d4118ab7bdf138d but since it only hurts the triple buffering patch, that's where it has been fixed: https://gitlab.gnome.org/Community/Ubuntu/mutter/-/commit/0b896518b2028d9c4d6ea44806d093fd33793689 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" because the bug is in auto mode (the default).
