The VideoLAN Forums

I just tested it, yep, everything plays fine when "Displays have separate Spaces" is turned on (log out was required). (though I keep it off so I can span windows across the displays) My initial thought was that maybe there's something about how MacOS creates a virtual desktop then cuts it...

I have two 2.5K DP displays (primary left, secondary right) each connected via a TB3 port on my system (MacBook Pro in clamshell mode), no other apps running. When I play / steam video and VLC is on the primary screen with the window within 55px of secondary screen, the video starts to get jumpy rat...
