I tried both. They partially fix it for me, but not completely. I still get a
single piece of the old view, though it is a much smaller piece than before. It
always happens if I first move forward and then turn sideways. And of course the
other noticable thing is that the window does not slide (scroll) but instead
just jumps from one view to the other.

I notice that if I obscure part of the window with another window and then
uncover it, that it is repainted with the corruption still there. By the way, I
can always get the window to repaint correctly by sliding my mouse down into the
area at the bottom where the books are kept. This might require the window focus
to be set to focus follows mouse.

I don't really have much of a feel for where the problem is. It appears to me
that the bitblt commands have the correct parameters, so like you I think this
is some sort of timing problem. I have the Xlib reference book that explains the
 XCopyArea command, but it does not mention any gotchas if the two Drawables are
the same. At the point I don't think I now enough to know how to attack it.
