Thanks. I can see a couple of problems with the machine now, which could cause this bug:

1. You have the old 'intel' graphics driver enabled. That's no longer being maintained and should not be used, especially on newer hardware like yours. Please ensure your Xorg config files do not load the 'intel' driver and if in doubt just uninstall it:

  sudo apt remove xserver-xorg-video-intel

You should be using the newer 'modesetting' driver which is also the default.

2. You have a number of extensions installed:

b'org.gnome.shell' b'enabled-extensions' b"['<email address hidden>', '<email address hidden>', '<email address hidden>', 'multi-monitors-add-on@spin83', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>', '<email address hidden>']"

so if removing the intel graphics driver hasn't already fixed the bug then please try to uninstall all of those extensions. Yes uninstall and not just disable, because a disabled extension can still interfere with the shell.
