[linux-f10-flashplugin11] Flash colors messed up, red shown as blue, probably due to the hardware acceleration

[Yuri]

All youtube videos appear to be bluish. Red color is displayed as blue.

Someone had similar issue on Ubuntu 
http://ubuntuforums.org/showthread.php?t=1977481 , and suggested 
solution there is to turn off the hardware acceleration in Settings.
But with the current BSD version (11.2.202.251) I can't turn off 
Acceleration for some reason. Check box keeps returning to "on" state.

This started happening with the new graphics card, which is NVidia 
GeForce GT 610. Same page in VirtualBox (Ubuntu guest) shows correctly, 
even though in the vbox guest flash also claims it runs with the 
hardware acceleration and version of flash is the same.

Is this a known problem, and is there any workaround?

Thank you,
Yuri
