Title:
Update gtk4 to 4.10.3
Status in gtk4 package in Ubuntu:
Fix Released
Status in gtk4 source package in Lunar:
In Progress
Bug description:
Impact
-----
There is a new point release in the stable GTK 4.10 series.
https://gitlab.gnome.org/GNOME/gtk/-/blob/4.10.3/NEWS
The version currently in Ubuntu 23.04 is 4.10.1
Test Case 0
-----------
gtk4 has an extensive build test suite, and failures will fail the build.
gtk4 also has thorough autopkgtests.
Ensure that the build succeeds and that the autopgktests pass.
Test Case 1
-----------
Make sure that opening and saving files from the Firefox and Chromium snaps
still work
Test Case 2
-----------
snap install portal-test
snap run portal-test
Verify that the app seems to still work ok
What Could Go Wrong
-------------------
Ubuntu includes xdg-desktop-portal-gnome by default which is used for many
snap actions like providing a file chooser. This is critical functionality for
our snaps.
The Ubuntu flavors use a different portal backend, most commonly xdg-
desktop-portal-gtk which uses GTK3 so it's not affected by this SRU.
Many of the default Ubuntu 23.04 desktop apps use GTK4. A serious
enough regression could severely break the Ubuntu Desktop.
gtk4 is included in the GNOME micro release exception.

Other Info
----------
The libadwaita autopkgtest needed to be updated to pass with gtk 4.10.3. This
is being handled with LP: #2019989
gtk4 needs to be updated before or at the same time as mutter 44.1 to
avoid a regression with artifacts near window borders. See LP:
#2020674 for the gtk4 fix and LP: #2020225 for the mutter 44.1 SRU.
