Comment 4 for bug 306895

I've the same issue both my ubuntu machines that are using nvidia chips with propietary drivers.

I've noticed the bug since when I've used kdenlive 0.7 (but it could be just a coincidence), however the problem happens also using mplayer, vlc or any other player that is using the Xv output (for example, I've no problems using the x11, or the gl/gl2 video outputs). It's anyway so strange since sometimes I've no blue-red swaps at all (generally after a fresh reboot), while the most time I use my PCs I get this issue.

I don't really know how I could fix this issue, but I guess that it could be a problem related to the nvidia-driver more than to ubuntu or other free libraries.
