     Running the dtest program on the PEX-SI on a SUN IPC with a dumb 8-bit 
     color display should perform the (pixmap) double buffering correctly. 
     However, if you have any of the other color options on your IPC, that 
     could be causing the problem. Since the image clearing is being performed
     by an XFillRectangle call, I don't see any reason why it shouldn't work.
