Bug Description

Impact
------
There is a new bugfix release in the stable 44 series.
https://gitlab.gnome.org/GNOME/mutter/-/blob/44.2/NEWS

This is basically a prerequisite for GNOME Shell 44.2 LP: #2022961

Test Case
---------
Complete the test case from

https://wiki.ubuntu.com/DesktopTeam/TestPlans/Mutter

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

https://wiki.ubuntu.com/StableReleaseUpdates/GNOME

Other Info
----------
This also includes an update of the triple buffering patch to add one commit to fix a potential crash with resuming from suspend. That triple buffering patch is maintained in a targeted mutter 44 branch by Canonical Desktop engineer Daniel. I was unable to easily reproduce the crash so I didn't include LP: #2020652 in the SRU changelog.

I dropped 2 patches to mark some tests as flaky since mutter seems to build reliably enough on Debian and Ubuntu without those patches.

Upstream assumes that people will be using matching versions of mutter and gnome-shell. To be cautious, I therefore bumped the dependency version in GNOME Shell 44.2 to require mutter >= 44.2 (even though GNOME Shell 44.2 appears to run ok with Mutter 44.1). I believe the only way to make the dependency relationship work the other way (not allow Mutter 44.2 with GNOME Shell 44.1) requires bumping the Breaks version but I don't think it's worth using Breaks unless necessary.

Hello Jeremy, or anyone else affected,

Accepted mutter into lunar-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/mutter/44.2-0ubuntu1 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-lunar to verification-done-lunar. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-lunar. 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.

The autopkgtest has passed now.

I successfully completed the Test Case with the Ubuntu, Ubuntu on Xorg, GNOME, and GNOME Classic sessions using mutter 44.2-0ubuntu1 on Ubuntu 23.04.

We still need to test Budgie to finish verification.

On Ubuntu Budgie 23.04

- Started with a fully updated system
- Enabled proposed and installed libmutter-12-0/lunar-proposed
- version 44.2-0ubuntu1 installed
- rebooted
- tested login / logout
- ran common applications to ensure windows worked correctly (focus, minimize, maximize, resize)
- changed resolutions, tested fractional scaling
- used the system how I would typically use it in my normal day to day scenario

I have not noticed any issues. The major problems I had with earlier versions (clicking title bars not focusing the window / clicking well outside the window registering as a click on the window) seem resolved.
