Are videos meant to tear with Metacity compositing?

Videos work great without composite, but when I enable metacity, videos tear slightly. I also notice a tearing line going from down up to.

It's quite hard to explain, the problem is that it's not syncing to VBlank!
Isn't there any way of enabling it? Will I have more luck with compiz?

Re: Are videos meant to tear with Metacity compositing?

Bumping after a week or so? I want to try using the compositing manager again, I have enabled VBlank syncing for videos/OpenGL but it still tears.

I see a line tearing from down to up, and the occasional normal tearing when things are moving quickly.

Same thing happens in ZSnes.
Am I doing something wrong?

Re: Are videos meant to tear with Metacity compositing?

Thanks, now I see this tearing too under metacity with composite enabled. Couldn't see it with compiz or no composite. Maybe you will try it out and report.

gna, this is probably the worst english I could write

No tearing with Compiz Fusion, I had to uninstall it within 5 minutes to stop myself from vomiting though.

Any ideas on how to fix the Metacity tearing problem?

I have the same, issue, to be honest I don't think the nvidia driver is able to prevent tearing with regular composite, the compiz fusion stuff is rendered with opengl.

When I remove the compositing, video playback with mplayer dont tear. Vsync=yes is in my mplayer config.

No tearing with Compiz Fusion, I had to uninstall it within 5 minutes to stop myself from vomiting though.

Compiz Fusion can be made to look identical to any Metacity theme with some work (and there's lots of pre-made themes), and you _can_ disable most of the effects. Why not do that?

Does Metacity with Xcompmgr work?

Do other video players work (VLC, Xine-based, ffmpeg-based, etc.)?
