This bug was fixed in the package mutter - 46.2-1ubuntu0.24.04.1
---------------
mutter (46.2-1ubuntu0.24.04.1) noble; urgency=medium
[ Daniel van Vugt ]
* New upstream release 46.2 (LP: #2068598)
- Fixed mouse clicks falling through to the window behind (LP: #2026194)
- Fixed a crash in meta_wayland_transaction_commit (LP: #2061739)
- Fixed night light getting stuck on (LP: #2066902)
* New upstream release 46.1 (LP: #2064735):
- Fixed blank screen on hybrid GPU machines using nouveau (LP: #2066931)
- Fixed a monitor hotplug crash (LP: #2050865)
- Improved performance on secondary GPU monitors (LP: #2038801)
* Refreshed patches:
- Support-Dynamic-triple-double-buffering.patch (LP: #2070437, LP: #2070438)
- meson-Do-not-mark-CI-test-tools-as-required.patch
- Mark-several-additional-tests-as-flaky.patch
* Add clutter/conform gesture tests to the list of known flaky ones:
it's a new test in Mutter 46 and not yet reliable.
* Add build-Compile-schemas-locally-for-use-in-build-tests.patch to compile
gsettings schemas for use in build tests. Debian CI requires this now and
it makes rebuilds more resilient against infrastructure changes.
* Add wayland-Disable-linux-drm-syncobj-v1.patch to avoid enabling major
new features in Noble updates, as detailed in:
https://lists.ubuntu.com/archives/ubuntu-release/2024-May/006087.html
* Add backends-Handle-null-views-instead-of-creating-dummy-view.patch
to prevent "clutter_frame_clock_notify_presented: code should not be
reached" log spam in some Nvidia Wayland sessions (LP: #1967707)
* Add backends-Restore-support-for-X11-cursor-themes.patch to restore
support for X11 cursor themes, which was lost in Mutter 46.0
(LP: #2062377, LP: #2063869)
[ Jeremy Bícha ]
* Stop compiling gsettings schemas in debian/rules
* Opt into Salsa CI
* Drop packaging references to Hurd since this is Linux-only
* Update libmutter-14-0.symbols
* Update Breaks
* Refreshed patches:
- window-Add-ability-to-override-the-edge-constraints.patch
- x11-Add-support-for-fractional-scaling-using-Randr.patch
* Drop upstreamed patches:
- Nvidia-secondary-GPU-copy-acceleration.patch
- compositor-sync-ring-Allow-the-gpu_fence-to-be-moved.patch
[ Marco Trevisan ]
* Add place-Always-center-initial-setup.patch (LP: #2016013)

Secondary GPU frame rates are held back by dynamic-max-render-time

Bug description:
[ Impact ]
Secondary GPU frame rates are held back by dynamic-max-render-time as
shown on this amdgpu setup connected to a 60 Hz monitor:
main: 30 FPS
main + CLUTTER_PAINT=disable-dynamic-max-render-time: 60 FPS
https://gitlab.gnome.org/GNOME/mutter/-/issues/3070
[ Test Plan ]
This is imprecise because many machines won't exhibit a measurable
difference...
1. Set up a dual GPU machine with dual monitors using an open source
driver such as amdgpu or nouveau. If you are using Mutter 46 or later
then the closed source Nvidia driver may also be used in theory.
2. In a Wayland session, check that the frame rate being achieved on
the monitor connected to the secondary GPU is at least that of the
refresh rate.
3. Add CLUTTER_PAINT=disable-dynamic-max-render-time to
/etc/environment and reboot.
4. In a Wayland session, check that the frame rate on the monitor
connected to the secondary GPU has not changed (didn't get better)
after the environment change.
5. Remove the change from /etc/environment.
[ Where problems could occur ]
Anywhere in frame scheduling and frame rate performance, since that is
what changed.
