-- Information about the crash:
Dolphin crashes on monitor turn on when DP is being used. The machine is working. I just turn off my monitor, go to lunch or something, when I return and turn on the monitor, Dolphin sometimes crashes immediately. It never happens if I'm using HDMI.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault

Actually this is a very old bug. I noticed it at least 2 years ago but I thought it's my old 1080Ti fault. Now I bought 4090 and the problem is still here.

This crash is deep in Qt. Lets take it upstream if we see issues with Qt6
Comment 3 mozo 2023-12-05 12:03:37 UTC
It's strange nobody report it for all these years. Is it only for my setup? I thought it's may be my old GTX 1080Ti but now I bought RTX 4090 and it's the same. I already tried three different DP cables. And it happens only in KDE.
