We did see this on Linux back with version ?.?. Suhaib had discovered
that it was a problem with X11 or Motif (I don't remember which). We
haven't seen it on the other platforms because the versions of X and
Motif have fixed this behavior. I don't know how one would fix this
with Irix unless SGI did something. You can try looking at the
caching functions, but when everybody upgraded RedHat and the problem
went away, I was pretty sure that Suhaib must have been correct.

I could not duplicate the problem on Linux or Windows, either. It seems to
just occur on Irix, which I believe Randall uses.
It seems to just be associated with red objects. I think that was always
the case. The cached images have red lines streaking across the image
originating from the red objects.
That pretty well describes it perfectly. This was a simple net running on
IRIX.
I was using volume rendering, it was a Color(red) volume with the background
voxels marked invalid), and the invalid render was red horizontal streaking
lines.
