Description

Hi!

If i enable display compositing on Xfce 4.8, movies in for example mplayer displays wrongly, it is like mplayer can´t render movies fast enough, it draws vertical lines on the screen, it only shows during fast sequences. If i disable compositing in window manager tweaks everything works as expected. This is reproducable in Xfce 4.6, 4.4 and 4.2 if i remember correctly. It is also reproducable on lots of different hardware, and not necessarily nvidia.

I have a nvidia 8800gt card using drivers 260.19.29.

Yes i know, this can be a Xorg issue, OpenGL issue or whatever issue but i must start somewhere because i´m tired of this problem, i want my compositing! :)

All i wonder is if this is a known problem with compositing in Xfce?

Version: 4.8.0
