I am using IDL with OpenLook, but I've seen the same behavior. The fix is to
call the routine "clear_colormap" immediately after exiting from X-windows. I
ensure this by running X-windows from inside a shell script with the following
line being "clear_colormap", i.e.
#!/usr/bin/csh
setenv IDL_DEVICE x
setenv OPENWINHOME /usr/openwin
$OPENWINHOME/bin/openwin -noauth $*
clear_colormap

I have experienced this. What is happening is that Wave is changing the
colormap for the Sparc. The base Wave color table (B/W Linear) causes plots
to be white lines on a black background. Unfortunately, this translates to
white letters on a white background once you exit X.
Doing a "clear_colormap" command, or reinvoking X will fix it. Alternatively,
the last thing you can do before exiting Wave is to load a color table where
the top value is black. The "prism" color table, number 6 I think, will do.
