I think I know what your problem is.  The Ardent X server has got some
serious problems with backing store.  It claims to provide it, but it 
doesn't.  Not only that, but it fails to provide expose events when called
for, since it apparently has fooled itself into thinking that the window
can be restored from backing store.  I suggest turning off the use of
backing store in twm and trying again.
