UI ingame problem.

haven't been able to choose resolution for few patches already ,but with recent patch the ui gotten worse! now shop window takes 90% of screen, the summoner name is half bigger than before and the whole graphics is not that sharp as it used to (chaeacter,stats numbers) I have highest graphics on. my biggest problem is the resolution window is completely blank on any windowed mode. maybe someone know solution?! https://imgur.com/a/pMUDi.png
