xorg.conf says 24, using proprietary ATI driver for the HD7700
DefaultDepth 24

verbose output of glxinfo indicates
doubleBuffer =1
rgba are all =8
depth =24
stencil =8
accum are all =16
doubleBuffer =1
system spec:
Intel Core i5
Radeon HD7700 graphics card.
Ubuntu 10.04
I am wondering if the ati proprietary driver might be to blame, but I am not sure how to check this...

auxBuffers=0 depthSize=24 stencilSize=8
accum: redSize=16 greenSize=16 blueSize=16 alphaSize=16
multiSample=0 multiSampleBuffers=0
