jit.gl.videoplane only showing top pixel (Windows 7 only - not mac)

Guessing it has something to do with opengl.

This patch is working on my macbook pro but not on the Windows 7 performance machine.
Any Ideas?

i can't reproduce.
what graphics card are you using?

It's a Matrox M-series. I'm not at the windows machine right now.

But one clue is, that jit.window shows only the topmost pixel of the file but it is stretched all the way down the screen. If I set the @noaccel 1, it works. This apparently disables opengl acceleration. When I put the video stream into the jit.gl.videoplane and use jit.gl.render to render the image to the jit.window it again only shows the topmost pixel. This time @noaccel 1 in the jit.window has no effect. Probably, because we are now in the opengl world, right?

I have downloaded the latest driver for the graphics card.

Any thoughts?

yeah, i'm not entirely sure those cards support opengl hardware rendering.
maybe send them a message to confirm.

does toggling @floating change anything?

Nope.

Same thing when floating and not. Also full screen.

I'll look at the Matrox compatibility with opengl.

It says on their webpage for this graphics card:
Opengl 2.0 support.

Should be alright then, right?
