I doubt the problem you're seeing is related to Ubuntu specifically.
It's more likely a configuration problem e.g. with the X drivers, or
perhaps you're using Compiz and your video hardware isn't up to it. Or
maybe you have a slow machine with only a small amount of RAM.

The reference is a good read. I'm not saying this is the problem he's seeing... I'm just saying its a new sort of problem that cropped up recently. Generally speaking the video driver or acceleration issues you brought up are more likely to be the problem..especially if it still happens when firefox is not running. We'd need much more information from the original poster to be sure.
