Title:
Include gtk4 changes needed for mutter 42.1
Status in gtk4 package in Ubuntu:
Fix Released
Status in gtk4 source package in Jammy:
Fix Released
Bug description:
Impact
------
We need to update gtk4 before updating mutter to 42.1. Otherwise, in gtk3
apps like gnome-text-editor, it's not possible to scroll past the cursor
position.
The mutter issue with more details is
https://gitlab.gnome.org/GNOME/mutter/-/issues/2261
We need to update mutter 42.1 since it includes a lot of bug fixes.
GNOME Shell 42.1 (with the corresponding changes to mutter, gtk3 and
gtk4) will better comply with the Wayland specifications.
The gtk3 bug is LP: #1972721
Test Case
---------
Install the updated gtk4 packages.
Use gnome-text-editor to open a long text file.
Scroll down past the page break.
The document should scroll normally.
What Could Go Wrong
-------------------
Ideally, GNOME would have done a new GTK4 release for this issue. They will
eventually, but it seems better for Ubuntu to be proactive and not further
delay the mutter/gnome-shell 42.1 releases.
These commits are cherry-picks from the stable branch
https://gitlab.gnome.org/GNOME/gtk/-/commits/gtk-4-6
NOTE
----
To avoid a temporary mismatch related to phased updates, we want this update
to be 100% phased before releasing mutter 42.1 to jammy-updates.
