1. Too short.
2. It fucked up my video driver. Not full on crash, but my screen went from HDR panel to a CRT from 1982. All I did was change from full screen to a windowed screen.
3. It killed my taskbar, and borked all instances of File Explorer. Happened when I made the above change, so I figure they must be related in some way.
A restart fixed lines two and three, but there's nothing I can do to fix line one. While I still had it set for windowed, I noticed the menus I would normally see at the bottom were off screen. When I pulled it back up to full screen, everything was there, though making the switch brought back the 80's. Now that I'm thinking of it, it could be a scaling issue between full screen and windowed.
