Client Bug
Adobe Air at it's finest
I assume this bug to be caused by the fix implemented when the client would crash, now it seems that the fix does stop the client from crashing after a game but it leads way to the client glitching up not only during the main page but also the champion select when you click too fast for the client to render the image of your champion skin. The image I posted is the first instance of it happening on the main page but it did occur after my game where the champ select bug occurred.
