This looks like a Windows 10 specific issue where Session Restore doesn't get the correct window dimensions from the widget code. Moving to the appropriate component to allow smarter people than I to check that out ;-)

Issue is reproducible on a Nightly from 2014(Fx 29.0a1), most likely not a regression.
