That strategy doesn't work when the layout of all the windows changes, since a window cannot be mapped at two places (and, potentially, sizes!) at once.

You could dump the contents of the workspace region to a pixmap, render that pixmap to a new (unmanaged) window covering the entire workspace, perform window movement/mapping behind it and unmap the covering window at the end. This would work, but it's ugly and complex. I doubt a simple and robust solution to this aesthetic issue can be conceived.

Cute. The generalization of this idea leads directly to a simple, robust solution: never unmap clients, and using OpenGL compositing to hide them instead. ;-)

It's worth noting that a number of desktop environments *have* moved to OpenGL for window management; I don't know if they use compositing per se, but windows are often implemented as OpenGL textures so they can be manipulated this way. -- brandon s allbery allbery.b@gmail.com wandering unix systems administrator (available) (412) 475-9364 vm/sms
