As in the title, some time ago every video that I open on Facebook using Google Chrome (with Firefox the problem doesn't occur) it's cropped into a smaller window (80-90% size) with scrolling bars to move inside. That is pretty annoying.
I tried to check if it was a zooming problem (CTRL+scroll) but it isn't, I tried to reinstall Chrome even cancelling user files, and I tried to reinstall the Flash player, even if as far as I know Chrome comes with the player inside.
Does anybody have an idea about what could it be?
