Seems to do the trick

Everyone using IDL 5.5 on Linux in 24bit TrueColor. It's a bug.
There is a workaround, in Tech Tip 3261 on the RSInc Web site.

Nope, it's Linux (and True64) 24 bit TrueColor specific.

the tech tip doesn't mention 32-bit color, which I _thought_ usually behaves
better with TrueColor apps (on Xwindows systems). Did you try setting your
system to 32bpp? My experience with XFree has been that many color-related
problems go away. The color depth is the same as with 24bit, but is handled
differently by the Xserver. Most modern cards have enough memory to handle
32bpp easily, if that helps, it's certainly better than going back to 8bpp
or 16bpp!
