No, in fact, I hated it, which is why I've given up on X11R3 for the RT
and gone back to running WM, the ITC's own window system. I
might suspect the Andrew stuff too, except that it runs fine on Suns
and Vaxen running R3. Most, if not all of the remaining apa16 (RT)
bugs stem from synchronization errors between the CPU and
display processor. One thing that helps is to only run on non-APC
RT's (they're only half the speed) -- that's what Palo Alto
developed/debugged the server on.

P.S. For those keeping track, I still see what appear to be line drawing
glitches, backing store failures, and font cache corruption.
