-- Information about the crash:
Hi KDE QA/Devs,

Often when I resume (from hibernate) my laptop (Dell XPS 9520) with the thunderbolt dock connected, the external second monitor is on, but only displays a black screen (but I can move the mouse in that area - Intel Alder Lake integrated P-GT2 GPU)

I waited 20-30s to see if it would finally display something, which it didn't and then unplugged the thunderbolt dock at which point I saw the KWin crash dialog - it's unclear if the KWin crash dialog appeared earlier on the second monitor, and the crash occured while resuming, and I only saw it when all windows were moved to the remaining laptop screen.

Happy to answer questions and will try to reproduce and comment back here (if this is not already a duplicate bug)

Many thanks for all the amazing work on KDE!
Andrew

The reporter is unsure if this crash is reproducible.
