Bug#639446: blender: Flicker in full-screen mode

[Dan McGrath]

I was looking through some of the blender bug reports and noticed this
report and figured I would add some more info to it.

I originally ran into this problem on Ubuntu 10.04 around the same
time you did, and filed a bug report at:

  https://projects.blender.org/tracker/?func=detail&aid=29230&group_id=9&atid=231

The problem seems to be gone for me now in Ubuntu 12.04, even if I svn
up back to the same revision that I reported it originally in, so I am
not entirely sure what actually fixed it (nvidia drivers, GL libs,
etc.).

Anyways, I mainly figured that I would at least point the people
monitoring this bug report to the upstream one. Hope it helps.
