description |
I installed mutter 44.1 and gnome-shell 44.1 from proposed, and a few of other related dependencies. I don't have everything at 44.1, I don't know if we should expect more gnome-related updates in lunar-proposed. For example, I have
gnome-shell-extension-prefs 44.1-0ubuntu1
but gnome-shell-extensions is at 44.0-1
Anyway, I wanted to report that I'm now seeing artifacts around window borders, when they are arranged to occupy all available area. I should note I'm also using gnome-shell-extension-ubuntu-tiling-assistant 39-3ubuntu2.
I'm attaching a screen recording of what I'm seeing.
The artifact at the border also happens across monitors. The tall chrome window on the right of the left monitor interferes with the windows aligned to the left of the right monitor.
This happened immediately after updating mutter and gnome shell to 44.1, it wasn't happening before.
So far I'm seeing them with just google-chrome and chromium (snap), but not other apps I quickly tried (gnome-terminal, firefox).
ProblemType: Bug
DistroRelease: Ubuntu 23.04
Package: libmutter-12-0 44.1-0ubuntu1
ProcVersionSignature: Ubuntu 6.2.0-20.20-generic 6.2.6
Uname: Linux 6.2.0-20-generic x86_64
ApportVersion: 2.26.1-0ubuntu2

SourcePackage: mutter
UpgradeStatus: No upgrade log present (probably fresh install) |
Impact
------
Mutter 44.1 switched from using the GL renderer to using Cairo to avoid rendering artifacts with the Nvidia drivers. However, this also needed a change in GTK4 to avoid other artifacts.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/2976
https://gitlab.gnome.org/GNOME/gtk/-/merge_requests/5857
Test Case
---------
Install gnome-shell 44.1 (currently in lunar-proposed).
Install this gtk4 update.
After installing the updates, log out and log back in.
Open a terminal and the Chromium web browser.
Tile the terminal to the left and tile Chromium to the right.
Verify that there aren't rectangle rendering artifacts near the border between the two apps.
What Could Go Wrong
-------------------
This is a one-line patch, cherry-picked from the gtk-4-10 branch that will be included in GTK 4.10.4 (which is expected to be released any day now). This puts us just a bit ahead of some other distros.
See the master bug LP: #2020708 for more details about what it means to update GTK4.
