had the same problem with flashvideos eg on youtube and deactivated desktop effects.
Just to let you know:
I just wanted to activate them again and couldn't. Something was preventing me from. I saw a running process named npviewer.bin on htop. Seems like it belongs to the flashplugin. I closed firefox und suddenly could activate desktop effects again.
