Description yamiyukisenpai 2021-10-04 03:12:16 UTC

SUMMARY
This doesn't immediately happen, but when I open another window, the screen flickers for a while.  Clicking seems to make it go away.

STEPS TO REPRODUCE
1. Put computer to sleep
2. Wake it up

OBSERVED RESULT
The desktop would wake up normally.  However, when you decide to open another window, that's when the flicker happens.

EXPECTED RESULT
App windows shouldn't have to flicker like that
