(Please keep it constructive, thanks.)

Would it help if we attach some dmesg with some value of drm.debug enabled? I
am also experiencing flashing/moving screens for some weeks now on Arch Linux
on SKL (i7-6700HQ) with Linux 4.6.5.

The "[drm:intel_cpu_fifo_underrun_irq_handler [i915]] *ERROR* CPU pipe A FIFO
underrun" message is sometimes logged when this happens for the first time in a
while. It seems more likely to happen when selecting text or moving close to
the screen borders.
