AMD iGPU - split-second graphical corruption on Linux 6.12.1

General system Kernel, boot, graphics & hardware

There are two possible solutions for now:

  • Switch to pre-6.12 kernel, probably the LTS one
  • Add amdgpu.dcdebugmask=0x10 to your kernel options to disable PSR (Panel Self Refresh) - it increases power draw, but fixes the glitches
