Comment 25 for bug 773861

The new version is an improvement to some extent. It looks I get more redraws than before. The skipping now seems more erratic than before. Please let me know if you want another video showing the behaviour.

I'm afraid however that from a user's perspective the difference is negligible; on systems suffering from this bug Unity is not in a very usable state. :(

In any case, your efforts are greatly appreciated. From what I can gather the root-cause seems to be NVidia's closed source driver not giving back correct data.
