Bug description:
[General information about the SRU]
* It includes the fix for the bug
https://gitlab.gnome.org/GNOME/metacity/-/issues/31
* The fix is already included in 3.46.0 release:
https://gitlab.gnome.org/GNOME/metacity/-/commit/77f1d55479bfef479f76011a1ee5636f9bf6b08b#9f621eb5fd3bcb2fa5c7bd228c9b1ad42edc46c8
* The reproducer also revealed another issue with docked windows, undocked
windows are not being restored after parent window is minimized and restored
* The fix for restore is included in 3.46.1 release:
https://gitlab.gnome.org/GNOME/metacity/-/commit/3db07fafa1c7ff9749b6a82ccb36d8b62f2304d9
* Focal(3.36.1) and Jammy (3.44.0) needs both fixes to be backported
[Impact]
This affects users using applications that have docked windows
[Test Case]
* Install gnome-session-flashback (metacity) and reproducer's dependencies
`sudo apt install lightdm gnome-session-flashback pyside2-tools
python3-pyside2.qtwidgets`
* Start a graphical session with metacity
* run python3 Untitled.py
* Undock one of the application's child windows
* Minimize main window
* Result: Metacity will crash
* Fix: install fix from ppa:
* sudo add-apt-repository ppa:mustafakemalgilor/lp-2003176-0
* sudo apt update
* sudo reboot # or alternatively, restart display manager
* run python3 Untitled.py
* Undock one of the application's child windows
* Minimize main window
* Expectation: it should not crash and the application should be minimized.
[Regression Potential]
The fix is small in size and localized, it should not cause any regressions.
