Peter fixed a load of stuff and it got merged in xserver master. Unfortunately there have not been any development releases of xserver master since that happened, but that will come in time.
If you are still seeing problems, and are definitely using xserver master, then I suggest explaining your problem here (if you are sure that you are seeing the same issue), or opening a new bug report (if it seems like your issue might be unrelated).
