Bug description:
  vdpau works very poorly in Ubuntu 12.04 LTS on Unity3d. Same 1080p
  movies use around 6-10% of cpu in 11.04 and 11.10 shoots up to 50-60%
  of cpu usage in 12.04 with vdpau and mplayer (all under Unity 3d) . I
  have tried several nvidia drivers and the results are the same (Nvidia
  current 295.40, 295.20 and 295.33 32 bits)  Videocard is Nvidia G105M

  This seems to be a Unity rather than a Nvidia bug as cpu usage drops
  back to around 6 -10% for same movies in Gnome shell.
