Isn't this the normal *X* behavior? ISTR the server+wm set as *the*
colormap, the one installed on the window having the focus. Hence one 
would observe exactly the same problem in a pure-X environment with 2 
windows having different colormaps. This is the famous 'colormap 
flashing' (and the reason why I avoid PseudoColor like the plague; 
nowadays almost any X-capable hardware has 24-bits TrueColor and it is 
much easier to emulate color-mapping than to use the X mechanisms for it).
