Can you describe exactly the sequence of events that you took to make this happen?

Comment 2 Oleg 2023-12-12 17:34:04 UTC

NO, i cant re-produce that bug anymore. it happened just once.

i suspect that it may be related to partial update state i had that moment,
updates where just installed and PC was not re-boot and may be some libs got messed up?

the actions i took was 

1) press [PrintScreen] then
2) close Spectacle window without doing any canges.

Comment 3 Nate Graham 2023-12-13 22:15:47 UTC

Yes, partial update states can cause this. That's why we recommend the "reboot after updating" style of updates as this kind of error won't happen.
