The reason for moving the elements offscreen was because a problem
with z-order was preventing us from guaranteeing the video windows
would be on top and in the correct order when we called hide and then
show. Calling hide and show resulted in a visual flash/glitch and
then nothing since the video was occluded by another window. A thread
about this problem, and how it effected other developers at the time,
To work around this bug, we set up the z-order once (correctly) and
then just slid the windows offscreen when they needed to be hidden.
When they were moved back into the visible part of the screen they
kept their initial and correct Z-order. This is why we did not hide
and show windows.
P.S. Many OLPC changelogs for activities at that time were in trac.
Here is the entry for the first release of record with this change
(two weeks after the SVN commit):
