I can not find a commit with shorthash 2d91b3b in the current Git tree. Can
you explain how you got your source tree exactly? An excerpt of "git log"
would probably help.

Can you explain how you arrived to that configuration? I tried with my
current X11 server (Intel HD), which has this: "depths (7): 24, 1, 4, 8, 15,
16, 32", and it works.
Also, please remember to send bug-reports to the users' mailing-list unless
you have a patch to fix them.
