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 BĂcha ] * 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) -- Daniel van Vugt <daniel.van.v...@canonical.com> Fri, 28 Jun 2024 17:35:12 +0800 ** Changed in: mutter (Ubuntu Noble) Status: Fix Committed => Fix Released -- 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/2070438 Title: Fullscreen direct scanout is not used if you enable the hidden experimental VRR feature in Mutter 46 Status in mutter package in Ubuntu: Fix Released Status in mutter source package in Noble: Fix Released Status in mutter source package in Oracular: Fix Released Bug description: [ Impact ] Fullscreen direct scanout is not used if you enable the hidden experimental VRR feature in Mutter 46. [ Test Plan ] 0. Find a monitor that is VRR capable. 1. Set CLUTTER_PAINT=damage-region in /etc/environment 2. gsettings set org.gnome.mutter experimental-features '["variable-refresh-rate"]' 3. Reboot. 4. Log into a Wayland session. 5. Don't panic. The screen is meant to turn red whenever something changes. 6. In Settings > Display verify that variable refresh rate is detected and enabled. 7. Open Google Chrome (Firefox won't work) and start an animation like https://www.vsynctester.com/ 8. Press F11 to make it full screen. 9. Verify the screen has now stopped being red. 10. Press F11 again to exit full screen. 11. Verify the screen has gone red again. If the screen went black at the end, don't panic. That's a separate bug 2066080. [ Where problems could occur ] Since the fix affects the runtime decision of whether to allow triple buffering or stay double buffering, the main risk is that triple buffering wouldn't be used in some situation where we would rather have it to maintain a smoother frame rate. [ Other Info ] First reported upstream in: https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1441#note_2062222 We DO NOT recommend enabling the VRR feature anyway because it is still buggy (bug 2066080) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mutter/+bug/2070438/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
