[CLIENT] Client resizes itself after games

Every time I've played a game today the client changes it's size from 1600 x 900 to 1280 x 720 after the game. In order to change the size back I've had to go to the option and first select the 1280 x 720 option then change it back to the 1600 x 900 option. I have done some testing with custom games and it only seems to happen if I enable the "Close client during game" option.

Has anyone else been having this problem? If so, I hope that Riot can get a fix in for it soon because while not game breaking it is fairly irritating. :/
