2) Under "uwm", when a window is resized using the f.resize function,
the application first receives an Exposure event, then a
ConfigureNotify event indicating the new height and width, and,
finally, a second Exposure event.
Right, because uwm pops up this little box displaying the size, and it
is popped up on top of the application. Unmapping that popup causes the
extra exposure. The best solution is to implement save-unders in the
server and have uwm set the save-under attribute for the popup. Another
solution is to place the popup outside the target window, so that some
other window gets the exposure instead.
