Screenshot after activity

S103 is an Open University application.  S103 opens a main navigation window,
which opens other windows depending on the activity chosen.  The window remains
in the background while the activities are taken place.

On exiting an activity, the main window should redraw its layout, but fails to
do so.

There is no console data to suggest why.

The application does not appear to have crashed, as it can be closed by
clicking on the X as normal, but it is not unusable and has to be loaded again
to continue.

I could upload a full +relay but it may miss the point (as an activity has to
be opened and closed to recreate the problem).  Would any other logs be more
helpful?
