Comment 7 for bug 1813511

I can only imagine this might be caused by suspend/resume crashing the gnome-shell process, and then it restarts (almost seamlessly) with a slightly different config.

Please run this command before and after suspend/resume:

  pidof gnome-shell

Do you find it gives a different answer after wakeup? If so then please follow these instructions:
