 Would you mind adding some printf debugging to see what the image endianness is?
 
 My setup (sgimips/be xserver, amd64/le client) prints that the default
 byte_order for the
 root window is MSB (big endian), which won't match the little-endian image data.
 
 My diff looks like this (it's from a bigger diff set, but you should
 be able to copy/paste
 the lines minus the '+' at the beginning into the right place,
 recompile and test.)
 
 ===
         XInitImage(image);
 
 +       printf("byte order: %d (msb=%d lsb=%d)\n",
 +           byte_order, MSBFirst, LSBFirst);
