Flash performance and black blocks

[Rune Maagensen]

Hi,

I'm getting pretty lousy performance out of Flash. Quite often when 
shifting between windows the flash object goes all black and only new 
animation is drawed to the screen. This isn't a big problem most of the 
time since it's all advertisemet.

But trying to play games on miniclip.com (bubble trouble) Flash just 
get's jerky, and unplayable.

The same game work flawlessly in Windows.

Is it possible to optimize flash on linux somehow?

my box is a p3 900 with a nvidia geforce2 gts and 384 MB ram, and 
currently running the latest nvidia driver from ubuntu.

TIA
