fsmenubar=0 causes fullscreen video performance problem (OSX)

davila's icon

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

Hi

Max Patch
Copy patch and select New From Clipboard in Max.

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

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