Seems to be bigger than the DE tough because I've tried a few different distros (not just debian) and various DE's all do roughly the same thing. I originally reported as a XOrg/Kernel change is causing this down the line. Still waiting to hear/see anything about how accurate that theory is though. The fact your bug has been open over a year and the issue persists even in 21.04 makes me think I'm about to get screwed out of a GPU and several screens.
Sadly this seems to be what I'm dealing with. Everything newer than 18.04 breaks once you have a second XScreen/GPU. https:/ /bugs.launchpad .net/ubuntu/ +source/ xfwm4/+ bug/1942477
