--- Comment #21 from rockorequin at hotmail.com ---
Ok, something has now triggered the flickering artefact in my 4.8.0-generic
kernel with that commit reverted. It didn't do it for quite a while after
rebooting.

This is all I can see in dsmg for drm:

[   16.587974] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun
[ 2561.138150] [drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU
pipe A FIFO underrun
