Agreed. :] I guess "you just trigger the events and hope the computer
can keep up".

Current sawfish has a comment for the save under in message window,
saying it was too slow. That was years ago, we could test, but I do
not have big hopes as most hints point towards compose and 3D tricks
as the future path.

I think the issue there is from the combined expose events on other
windows (like a normal move) plus the app trying to reorganize all its
own widgets. I have been using opaque modes for ages but I rarely
resize interactively, so I have never been affected much. And in
systems that "do resize right" all I noticed is the mouse was in
different place than the window (which, yes, was redrawn "fine"... at
in a slide show speed).
