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.
