No you don't miss something :-)
You are right, installing xserver-xgl is NOT a FIX.
My problem was that I had no shadows. (hardy 64-bit, Geforce 8600 GT)
I installed the official driver manually and my shadows were back, so it is a problem of the ubuntu package, I think.
I would NOT recommend people to install xserver-xgl!!!
