Weird X11 behaviour

[thomaskr]

steps to reproduce

1.) install a fresh 24.04 ubuntu

2.) change /etc/gdm3/custom.conf to
a.) enable autologin
b.) disable Wayland so you have entries like these:

WaylandEnable=false
AutomaticLoginEnable = true
AutomaticLogin = user1

3.) install thonny - as an example app (apt-get install thonny)

4.) reboot system

5.) start firefox or any other app in full screen mode

6.) start thonny

7.) maximize thonny window

8.) click into the shell tab at the bottom of thonny

for unclear reasons you are switched to firefox

the problem does not occur on wayland.

the problem also does not occur if autologin is turned off

In the absence of any action in response to comment #1 I'm moving this to the gnome-shell package so that it at least comes to the attention of Ubuntu's Desktop Team.

@thomaskr, please execute the following command only once, as it will automatically gather debugging information, in a terminal:

  apport-collect 2066898

When reporting bugs in the future please use apport by using 'ubuntu-bug' and the name of the package affected. You can learn more about this functionality at https://wiki.ubuntu.com/ReportingBugs.
