Looking at glxinfo from the git server, it does look like your root
visual isn't actually double-buffered:

0x21 is the root visual and it should have a 'Y' in the db column if
it was double buffered.  The new visual code should pick a double
buffered fbconfig for the root visual, but clearly that doesn't
happen.  Also, the root visual has accum buffers, which is pretty
broken.  I'm guessing the new code has some problems with 16bpp, I'll
take a closer look.
