Same problem happens often on my desktop PC when resuming from power saving
mode with monitor switched off. Like in other cases, switching monitor off/on
helps but all open windows although seemingly restored to the original size
before power saving, must have been temporarily resized to 640x480 during DP
resolution negotiation which results in XFCE compiz (another, unrelated bug)
shrinking them to 640x480 after moving for example.

Issue occurs very often, maybe about 1 of 5 times power saving mode is on. I am
happy to do some more debugging if pointed to the right direction how to do it.

Some specs:
AMD RX5700 (Navi 10)
MSI MAG321CURV monitor.
