Life on July 20 and there is not enough time under normal Stable Release
Update procedures for this fix to land in kinetic-updates before July

Bug description:
[Impact]
gnome-control-center crashed when switching to mirror mode and monitors don't
have matched resolution
[Test case]
Mirror mode is only an option if there are only 2 monitors connected even if
one monitor is disabled. A laptop's internal screen counts as one of the
monitors.
1. Connected monitors to system which don't have same resolution.
2. Open the GNOME Settings app (gnome-control-center)
3. On the left sidebar, click Displays to switch to the Display panel
4. Switch to mirror mode
3. gnome-control-center won't crash
[Where problems could occur]
It only modified the code related to mirror mode in Displays panel. For KK
and LL check variable (best_mode) before using it. For Jammy, modified the way
to find cloning mode and check the variable (best_mode) . The second patch
already included in gnome-42. The risk will be low.
[Other info]
Two Merge Request are related
1. Check best_mode exist before adding flag
(https://gitlab.gnome.org/GNOME/gnome-control-center/-/merge_requests/1835)
2. Use virtual clone modes when mirroring
