It is the 'normal' way but I'm not sure it's the 'preferred' one for a x64 system.

Seriously, are you SURE you tried the x64 version? From the looks of it, you didn't, so I'd suggest you following the steps to get the x64 package.

Something like this should work: http://nxadm.wordpress.com/2009/04/26/install-64-bit-adobe-f... http://www.cyberciti.biz/tips/install-flash-10-ubuntu-linux-...

It's not flashplugin-nonfree, as the x64 version is still a beta package available separately (but drastically better than the standard one on x64 machines).

I had definitely tried that before, recall issuing a 'mkdir .mozilla/plugins' & moving a .so in there. Can't remember why I rolled that back and reinstalled it through apt thought.

Anyways trying it again nonetheless, the blinking is still going on with scrolling, going to see if performance/crashing at least improves.
