Hi, all, 

   There used to be a big problem working with Mathematica on systems (at least those using XOrg) which had compositing turned on (fonts being faded, 3D plots not showing up, etc.). That all seemed to have been solved until recently.

   I have version 7.0.0 running on a 32-bit linux system, in KDE 4.2 (radeonhd driver). Now, most of the stuff is esoteric, and I'm quite happy to have gotten everything running fast and stably and prettily, including Mathematica looking great. However, I've just noticed today that if I produce any 3D graphics (using Plot3D, or Graphics3D[Cylinder[{{0, 0, 0}, {0, 1, 0}}]], for example) that the 3D object shows up only if I'm actively rotating it or resizing it with the mouse. Otherwise, it disappears and looks like just a big blank space on the screen. I might try updating to 7.0.2 just in case that fixes things.

    I can happily provide more details if anyone thinks they can help (though I'd have to be told which details might be important). 

                   Curtis O.
