Public bug reported: [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. ** Affects: mutter Importance: Unknown Status: Unknown ** Affects: mutter (Ubuntu) Importance: Medium Assignee: Daniel van Vugt (vanvugt) Status: In Progress ** Tags: impish nvidia performance ** Bug watch added: gitlab.gnome.org/GNOME/mutter/-/issues #1758 https://gitlab.gnome.org/GNOME/mutter/-/issues/1758 ** Also affects: mutter via https://gitlab.gnome.org/GNOME/mutter/-/issues/1758 Importance: Unknown Status: Unknown ** Summary changed: - [nvidia] Animations stutter constantly on Nvidia in GNOME 40 + Animations stutter constantly on Nvidia in GNOME 40 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mutter in Ubuntu. https://bugs.launchpad.net/bugs/1946204 Title: Animations stutter constantly on Nvidia in GNOME 40 Status in Mutter: Unknown Status in mutter package in Ubuntu: In Progress Bug description: [Impact] Animations stutter constantly on Nvidia in GNOME 40.
