Thanks Carl for the information. I will look into the cairo-directfb commit which you have mentioned and I will be more than happy to provide any help.

Thanks,

Well, since changing cairo alone changes the behavior, then I think
the cairo list would have been the "right" place, but no matter. You
still found someone who can answer.

This sounds like a recently reported bug in cairo's directfb
backend. There's an open bugzilla entry for the issue here:

       [directfb] Regression in 1.6, making gtk/directfb not repaint
       changed window areas correctly

       https://bugs.freedesktop.org/show_bug.cgi?id=15652

And the discussion there points to this as being the problematic
commit, (reverting it fixes the problems encountered by one reporter):

       [cairo-directfb] Merging from directfb.org

       http://cgit.freedesktop.org/cairo/commit/?id=08516d97a1b34cbb119d6d842ae31e4cb4e08740

Sadly, that commit is doing 9 independent changes in one commit, so
it's not trivial, (particularly for me, knowing nothing about
directfb), to identify and revert or fix the single buggy piece.

Any help you might be able to provide further would be appreciated, of
course.
