Yes I remembered this after I've sent the letter. I was thinking about
this double-buffering issue. The main problem seems to be how to
"erase Tray contents in the background" - Qt just asks X11 to repaint
an area occupied by Tray to erase it so it could hardly be done
in-memory. I've posted some questions to forums so we'll see if there
is a solution.

Valentine.
