Problem:
Wehn some activities are open (especially Browse), and then the frame is
shown, when the frame "slides" off the screen the area under the frame
takes a while to redraw, leaving a mess of parts of the frame or partially
drawn controls, which is visually confusing.
Solution 1: Set the save-under flag for the frame window in X if
possible. This uses additional memory while the frame is showing, so it
might not be practical.
Solution 2: Have the frame visually "slide out" but don't actually move
the X window. Instead replace the area with plain light grey. When the
slide is complete, remove the now all grey window, so the redraw happens
in one go. That way the frame still shows the sliding animation as a
visual aide in finding it again, but the redraw can be made neater.
Solution 3: Do not slide the frame when in the activities view.
