I've been searching google and this forum for some time and wasn't able to find anything on this, if there is a thread already, sorry.

So I have a Radeon 9800 PRO 128MB, and running FC6. I used the open-source drivers for some time, but I want to switch to the proprietary, I've used them in FC5 and had no problem whatsoever (except the lack of the "Composite" extension, but I don't care that much for eye-candy anyway).

The thing is that since I've installed them (first 8.29 and now 8.30), I have no transparency (rounded corners for windows have a black background, bubble-like popups and tooltips are rectangular, the bouncing icon cursor has a square black background etc.). If I switch to radeon it works just fine, but I don't get high enough frame-rates in OpenGL apps.

I get the problem in both KDE&gnome.

Here is a collection of screenies showing the issue:
