google "bucket tests" many different changes....one of the changes they have been testing was no buttons...but I believe moving your mouse would cause the buttons to slowly appear.
its not necessarily the cause here...but any time you notice any Google changes...its possible its Google experimenting. They get so much traffic that they pretty much let anyone try anything, no matter how outlandish, with very tiny subsets of visitors.
If thats the case, clearing your cache/cookies should make it go back to normal.
