Hello,
Installed fresh manjaro kde on precision 5470 with 12th gen 12800H cpu.
During the boot (dell logo) the right side of the screen starts flashing, like this post.
This glitch occurs on 60hz only on both wayland and x11. As soon as I plug into a dock with 2 external monitors, the issue disappears. Also the issue disappears if I set to 48hz refresh rate.
The solution in the post linked above, is to set i915.enable_psr=0
this disables power management of the gpu and is not a permanent solution, especially since it helps degrade the laptop battery.
I am looking for some hints at how I can resolve this
