That is a very loosely-worded, poorly-described bug.

If you go to ATI's driver download site, what's the latest Catalyst
driver for your GPU?

I can't do this for you - you don't specify whether it's a desktop or
notebook, card or integrated, 32-bit or 64-bit Ubuntu, anything much,
so I can't go through the selection screens for you.

When you find what version of the driver is current, what versions of
Ubuntu support that driver?

Again, not enough information. We are not psychic, we can't guess.
What driver /is/ X.org using on your pre-release test system?

Not for sure without much more info, no.

At an unsubstantiated guess:

* The version of Catalyst for your card isn't supported any more in
the 12.10/13.04/13.10 version of X.org and so on, which the 12.04-1
/et seq/ releases use. So you have fallen back to unaccelerated 2D
graphics.

* On the prerelease install, it's using the FOSS driver, called
"radeon", because no supported version of the Catalyst drivers is
available.
