system specs from "about system"

Taking a screenshot with spectacle as well as flameshot shows wrong (old) screen content - only in multi screen environment (X11 as well as wayland) on both the primary as well as the secondary screen. 

Sometimes it helps to place the mouse pointer on the primary screen.
As well as disconnecting the secondary screen and re-connect it again. 

STEPS TO REPRODUCE
Takes place randomly, usually after a while, first screenshot mostly works.

OBSERVED RESULT
The screen content is missing some application windows or even shows already closed windows.

EXPECTED RESULT

> spectacle as well as flameshot
Since it affects both apps, I'd lean towards this being caused by a GPU driver issue.
Comment 2 Andreas Petzold 2023-05-24 11:21:54 UTC 
Similar problem here on fedora 38, plasma 5.27.5, spectacle 23.04. My Lenovo laptop has an integrated intel gpu.

I can confirm this bug.

I have 3 Screens and when i try to capture screen 1, the screen shows content from screen 2, but displaced.

Can you provide more details about your setup? `qdbus org.kde.KWin /KWin supportInformation` what screen are you taking a screenshot of?
