I did a minor tweak to fix the problem with 24-bit rendering (bugzilla #1555), but now I notice something else strange. In 1400x1050x24-bit (according to xdpyinfo, but I don't think that's right), I am able to resize a glxgears window such that part of the gears image is repeated, offset to the right, in the gears window. I'm not able to reproduce this in 16-bit. I don't think my change cause the problem, but, since rendering is complete garbage without it, it's impossible to tell for sure.
