I've just solved one problem with my graphics, only to run into a new one. I've got an ATI Radeon card and I've installed the Ubuntu-included fglrx drivers for it. That gave me hardware-supported graphics, which is nice.
However, now I got a new problem: My (up to date) Chrome browser frequently gets its content messed up -- sometimes the tab bar, sometimes the page contents:
That did not use to happen so I believe it's directly linked to the switch to fglrx. I was using default Ubuntu drivers before.
--> How can I fix this (without losing hardware graphics support again)?
