Bug with the Client?

Hi, I noticed on my windows computer, when I plug the HDMI to a large screen and use my computer, and open LoL, THEN unplug it and use it on my normal PC screen, the league client becomes very weird. The bottom part of the screen goes completely missing and the resolution goes down by a level. Even if I change the resolution back it will still have the bottom part of the screen cut off.

Only way to fix is to close the client and reopen it.

Anyone else with this problem?
