What Could Go Wrong
-------------------
Mutter is an essential component of the default Ubuntu desktop and for the desktop used by Ubuntu Budgie.

A severe enough bug could mean that people are unable to use their desktop version of Ubuntu.

Smaller bugs could interrupt people's workflows.

mutter is part of GNOME Core and is included in the GNOME micro release exception

This bug was fixed in the package mutter - 42.4-2ubuntu1

---------------
mutter (42.4-2ubuntu1) kinetic; urgency=medium

  * Merge from Debian unstable (LP: #1985856). Remaining changes:
    - Add triple-buffering patch
    - Add x11-Add-support-for-fractional-scaling-using-Randr.patch:
      + X11: Add support for fractional scaling using Randr
    - Add ubuntu/wayland-data-device-Allow-any-drag-timestamp....patch
      + Allow any drag timestamp as drag start serial
    - Add backends-native-kms-crtc-Don-t-compare-gamma-values-on-un.patch
      + Avoid memory errors when comparing gamma values

    - Add patches from GNOME !2364
      + Fix X11 selection related crash when Xwayland died
    - debian/libmutter-10-0.symbols: Add symbols for triple buffering patch

mutter (42.4-2) unstable; urgency=medium

  * Team upload
  * d/control.in, d/gbp.conf: Set up branches for an unstable upload
  * d/p/tests-Give-mutter-test-runner-the-RUNPATH-to-find-Clutter.patch:
    Add patch to fix missing RUNPATH in tests, fixing an autopkgtest
    regression in 42.4.
    - Note that this does not resolve a different autopkgtest regression
      in 42.4, in environments where /dev/dri/card0 exists but is
      inaccessible. However, the /dev/dri/card0 issue is not fatal for
      Debian's production infrastructure, which uses autopkgtest-virt-lxc
      and therefore does not provide /dev/dri/card0 at all.

Hello Marco, or anyone else affected,

Accepted mutter into jammy-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/mutter/42.5-0ubuntu1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, what testing has been performed on the package and change the tag from verification-needed-jammy to verification-done-jammy. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-jammy. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Ubuntu SRU Bot (ubuntu-sru-bot)]

Thank you!

I tested 42.5-0ubuntu1 on a Z13 (which prompted the heuristics change) and can confirm it's working with Wayland and the non-functional resolutions are no longer offered.

libmutter10-0/42.5-0ubuntu1 installed on ubuntu-budgie

No regressions noted. Dual monitor - maximise, minimise, workspace movement etc etc.

The verification of the Stable Release Update for mutter has completed successfully and the package is now being released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.
