I&#x27;ve been running Mate and Gnome3 for the past 6 months as well. Mate had some issues and, for both, the screen went black for 1-2 seconds when videos start playing.<p>I was able to get a compositor (Compiz) working on Mate and this fixed the tearing issue. It had some issues where it just kept crashing and rebooting that I never figured out. So I switched back to Gnome3. Although Gnome3 comes with a compositor (I think? And I think it might be Compiz?), I can&#x27;t seem to get rid of the screen going black when a video starts.<p>But it really doesn&#x27;t make a big difference and it&#x27;s not a big enough annoyance to matter. I don&#x27;t really use FreeBSD for media anyway. It&#x27;s just the auto-play videos on Facebook that triggers the infrequent frustration.
