legacy x-windows buggy behavior in 64-bit maverick

[Art Edwards]

I'm trying to use silvaco's simulation suite, which uses a very
old-style x-windows tool-kit. Some of the windows are rendered
incorrectly. They work on RH. We have tried forwarding X from a 64-bit
RH box, where the graphics are rendered flawlessly,  to the ubuntu box,
but this gives the same behavior.

Any ideas are welcome.
