Another thingy - modt likely related. When I have my 4k USBC monitor plugged in, then it goes white instead of my main laptop screen. Unless I log out - then both will go out. Yet in its first phase when only 4k monitor is white it seems it might be an issue with full-screen windows. Ie if I swap any app that is in FOREGROUND to window mode white screen dissapears. Then if I switch to any app from background, and put it on foreground the screen goes white again. Swapping back to windowed mode shows desktop with an app again. In this state when I lock my screen it goes permanently white on both screens (100% of cases). Most likely because the lock screen is set to fullscreen, and not windowed. I'll try to reproduce and append dmesg logs here if it happens.

Issue description: Originally, I started with ubuntu 22 which had several missing Drivers. One of the Problems was that the sceen would sometimes freak out with partial white flashing which quickly worsens until the whole screen turns white. The OS keeps running. I can still hear audio and the mouse is still being rendered ontop of the white screen, changing when I hover over elements. I have also had success when logging out on the top right corner through trial and error (since I cannot see whats behing the white screen). Restarting the Machine or logging out resolves the issue Temporarily. I have tried several things with varying success: - I have tried installing KDE plasma, which did not fix the issue - I have tried switching GPU Drivers (530 or 535 is the offered one in ubuntu, also tried the generic driver with the same issue) Allegedly this problem is known with these nvidia driver versions so I tried to install version 550 manually, but that led into a boot loop. - I have installed ubuntu 24.04 and upgraded the kernel to 6.9-RC6, which greatly improved on the issue compared to ubuntu 22.04. However is is still almost 100% reproducible when starting full screen applications such as a game or going into full screen on youtube - I have lowered the screen refresh rate from 244hz to 60hz, which also reduced the frequency of the issue appearing. I can now watch youtube on full screen most of the time but playing a game for instance still does not work As for the requested kernel information, I cannot find how to attach a "separate attachment" here.
