[Bug 1561729] Re: [drm:intel_cpu_fifo_underrun_irq_handler [i915_bpo]] *ERROR* CPU pipe A FIFO underrun

 

Hey!

I'm also facing this problem, I recorded a video about it:

I tried to move away from XOrg, by using GNOME+Wayland, but, problem
persist, Wayland is faster, however, I can still see it flickering
(faster).

Problem with GNOME+Wayland is that it completely freezes my Macbook.
