Well, the byteorder and colormasks are very different between Cygwin/X 
and Exceed. Since we have white becoming yellow, I suspect CDE gets 
confused by the pixmap depth=32/bpp=32 and sends the 4th (padding) byte 
first when it should be last, or something like that. Question for 
gurus/developpers: is it possible to disable that pixmap format?
