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 up per display that causes a reduction in display frame rate, but it was odd that it was only if the window was in that small region (which also falls entirely on a single display)… Also, QuickTime doesn’t have the issue (different method of display?), so maybe it’s the method VLC is using to render the video to the display (I wasn’t sure if there was some settings I could tweak and try). The only other app I’ve noticed with this issue is OpenOffice/LibreOffice, the interface is sometimes very laggy when near the screen seam (but from either side), but turning off it’s setting “Use Skia for all rendering” solves that.
Do you have multiple screens? Does it do this for you as well? (to tell if it’s somehow hardware related to my setup, cables maybe?)
