Public bug reported:

I have a Lenovo Legion 7 Laptop with AMD 7000 series APU and dedicated
NVIDIA RTX 4060 GPU.

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.

Best regards,

Julian Bechtold
