This isn’t a big deal, but when windows are minimised using ctrl+alt+i in beta a red outline/boarder of the window remains. Like I said it’s not causing any functional issues, just cosmetic.
I'm trying to replicate (with composite dis/enabled) but it doesn't happen to me E16.
Might be a very machine specific thingy.
Knowing me yes. I’ll post a screenshot when I get a spare five minutes.
