I was also experiencing "smurfs" in youtube - having NVidia 8500 GPU I was not able to turn on HW acceleration to get rid of this as this caused frequent crashes with other sites, namely and especially with Yle Areena ( http://yle.fi/areena )

For 12.04 the installation directory seems to have changed.
What I did was as follows:
First checking where this file is:
So the libflashplayer is now there, lets go there as well:
$ locate libflashplayer.so
Making a back up never hurts - so backing up the file before changing it
$ cd /usr/lib/flashplugin-installer
Now - this did it for me. YMMV. If it does not work you should be able to revert the changes by returning to the backup file (if you made one) or uninstalling / installing the flash.
$ sudo cp libflashplayer.so libflashplayer.so.bak
$ sudo perl -pi.bak -e 's/libvdpau/lixvdpau/g' libflashplayer.so
Thanks to UB - newbie on this - hopefully now I can enjoy all web video content without griefs of the flash player.
$ sudo cp libflashplayer.so.bak libflashplayer.so
