Never had any issue like this until I had to replace a monitor, and the newer one doesn’t keep HDMI/DP signals alive at all when the display sleeps, causing Windows to think it disconnects.
It’s such a stupid and common thing that the “PersistentWindows” tool exists to put the windows back in position after W10 fucks up everything from the monitor disconnect. So it’s not a stretch to think dwm.exe has issues with it as well.
