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
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.
