Firefox 4 Beta 7 seems to install correctly and also starts without errors, but
it fails to actually render the program inside the window decorations.
The title in the window decoration still shows that the program is functional
(though invisible), as I it updates with a new title if I go to a new page
(using Crtl+L shortcut and type the address blindly) or open a new tab
(Crtl+T).

Beta 6 works fine and I believe one of the changes to Beta 7 was the
introduction of GPU acceleration by default, which I suggest could be causing
the problem, though I'm not sure. I'm using Ubuntu 10.10 with a Radeon X1300
Mobility and the default open source driver from the distribution. In case it
is the GPU acceleration causing problems, I guess it could be a bug in the
driver instead?
