Hello, First sorry for the late reply, it was nighttime here. Thank you for the idea, it did make it happen less, but it didn’t fully solve it. Just for a clarification it is the laptop monitor that does that. Now I did start experimenting with kernel parameters and have stumbled across a post on free desktop gitlab, it’s AMD DRM issue 3827, “Lenovo T14 Gen 5 AMD 780M 2.8k panel screen artifact/flicker when using display at 120Hz” (didn’t allow me to post a link)
I tried various combinations but ultimately when I set amdgpu.dcdebugmask=0x200 and removed the amdgpu.sg_display=0 flag. The issue seems to be gone, but I will need much more testing than I did currently. (Rebooted the laptop like 5 times). But again huge thank you, you are the first person that actually replied to me. Will keep this page updated if I did manage to solve it. It could potentially help someone.
