Title:
Black flicker when leaving monitor
Status in linux package in Ubuntu:
Incomplete
Bug description:
Sometimes, when moving cursor from one monitor to the other, the
external monitor turns black and gets back on again.
The hardware is Dell Latitude E5470 with Docking Station and monitor
connected via DisplayPort (checked both ports and happens on both of
them).
Everything worked correctly on Ubuntu 16.04, but it happens on Ubuntu
16.10. Kernel 4.8.0-25-generic.
The bug isn't related to cursor only, if focus changes by alt+tab it
sometimes happens as well.
