Comment 37 for bug 938658

FuzzyQ i can only think of a couple of things at this point

1.Type unity --version in a terminal and make sure you are running 5.10
2.Upload a video showing you are still having problems with windows blanking when you maximize from launcher.
3.The window focus problems are a different bug than this one, i suggest looking through the bug database and finding another similar report or start your own if you can't find another.

The developers are still polishing the unity bugs so be sure to update every day and i'm sure it will be sorted before launch day.
