This may be an easy fix, I'm unsure of what keywords to use to find it. I have a three monitor set up, each monitor with a different DPI and resolution. When I'm playing a fullscreen video on my top monitor, the top of the bar of the window of the application on my bottom monitor will appear over the bottom of my top monitor. This only occurs if I have a fullscreen video playing. You can see in my attachment what I mean.

How do I solve this?
