Configuration: Vaxstation 3100 running ultrix 3.1
               Xserver: Xqvss from the X11R4 mit tape


Some X programs (that use special GC's like xor) do not display correct
on my Xqvss server. When I change display to a Xsun server on a SPARC 
(also form the mit tape) but the client is still running on the same,
original host, the programs display fine.

The programs that show this malfunction are:

- Rochester connectionist simulator

- drawbox , a prolog interface to simple Xlib calls like drawing lines, circles
  text etc. . (

- Xchess, probably the best known of these three programs. The pieces that are
  on a black field are not correctly displayed, (Xchess uses outline bitmaps, 
  mask bitmaps and GXcopy, GXor, GXandInverted, GXinvert contexts)


Any hints are welcome,
