Fix for strange colours when playing movies
I’ve an NVidia card with driver version 169. Sometimes when playing movies with Totem, the colours would be off. It took me a while to figure it out, thinking it was maybe a bug I couldn’t do anything about except for downgrading the NVidia driver (which seemed like too much work with Fedora).. Not sure exactly where the bug lies, but the hue setting for XV changes sometimes, resulting in odd colours. I think gstreamer may reset it sometimes. The quick fix is to install xvattr and run the following:
xvattr -a XV_HUE -v 0.
