fsmenubar=0 causes fullscreen video performance problem (OSX)

When I set fsmenubar=0 in a fullscreen jit.window (or ;max hidemenubar). The video jumps a lot.

here my video and window settings:

jit.qt.movie @preroll 1 @adapt 1 @highquality 1
jit.window “Video Rack” @interp 1

Any suggestions?
Thanks a lot

Sorry about the details. Some tests later I have more data.

Two settings cause jumps in video playback

1. If I set fsmenubar=0 and fullscreen in the laptop screen
2. If I set fullscreen (no matter the value of fsmenubar) in a second screen

Otherwise, I mean fullscreen in laptop screen with fsmenubar = 1, the video runs smoothly

If you update to 5.1.1 the problem has been fixed! You can also change the readback mode for opengl with the following:

– Pasted Max Patch, click to expand. –

Using ‘fbo’ fixes the problem pre 5.1.1 but it doesn’t perform very well on intel graphics chips (default setting is ‘rtt’)
