Likely the same issue as identified in bug 788829.

Can reproduce in kwin also.

We'll track given this is a new regression, but wouldn't hold the release for a fix.

Assigning to Neil to take a look, re-assign to another person if need be but at this point in the cycles we need there to be a real person assigned to tracked bugs.

Fixed in bug 788829

I do not understand that why Target Milestone is mozilla18. Please fix Firfox17beta.

I moved all the flags requests to bug 788829, so we can now actually keep this is a dupe.
