I am also affected by this bug under my Gentoo system:
Are you sure Nvidia is choosing the proper option? Like pointed by Anssi, seems that nvidia drivers are requiring workarounds in many players for working properly with them. I am a bit tired of this endless dicussion between developers from totem and nvidia about how to handle this properly. Seems that this is broken since 2005, how many more years will we need to wait?
Thanks a lot for understanding it :-)
