Bug#1076708: short screen blackouts on intel iris+ 640 gpu when watching videos, reports of CPU pipe FIFO underrun errors from i915 module in logs

[Piotr Morgwai Kotarbinski]

I've just replicated this bug on Ubuntu-24.04 (kernel 6.8.0-39-generic), so it 
seems to be an upstream bug rather than a Debian specific.
