Title:
[Star LabTop (Mk III)] Screen backlight pulses rapidly when cursor is
still, but i915.enable_psr=0 fixes it
Status in linux package in Ubuntu:
Confirmed
Bug description:
The backlight for my display appears to brighten and dim rapidly
whenever the mouse cursor is still, but stops when the cursor is being
moved. The pulsing backlight is distracting and causes eye strain.
Same issue experienced on Ubuntu 19.04 before upgrading.
