Comment 15 for bug 474134

1. Nobody did anything specific, the problem seems to have been present right from the start for everybody (after an upgrade or fresh install). Most people here seem to use a Radeon Mobility graphics card.

2. Expected: normal behavior

3. Encountered: see screenshot above, same for notify-osd. The content is still somewhat shown, but heavily distorted & "tiled".

Please follow all the links provided here, they provide plenty of information.
