Windows are resized and reordered upon resume from lock or suspend

[Kyle Weber]

After a resume from a lock/suspend, windows sizes are changed, fonts are incorrect sizes (until mouse over), and windows have moved from the secondary monitor to the primary monitor. This happens every time the displays have been off (from a suspend or lock screen). AMD graphics with dual 4K displays.

The XorgLog files seem to show at least one of the monitors being redetected, like it was unplugged and replugged. If Xorg thinks that's happening then yes windows would move to one screen. Please try a different DisplayPort cable.

Also, please check that your gnome-shell process ID is the same before and after lock/suspend, by running:

  pidof gnome-shell

both before and after.

It's still doing it with the same process ID. I switched DP cables--perhaps it's a bad port on the board or display... I'll look into it further. Thanks for your assistance!
