Client Bug - top left Close (X) button not responding

Location - Client

Bug - The close button at the top of the screen won't respond to clicks

I've had this happen twice so far since I started playing on patch 6. 2, and some of my friends and roommate have had the same issue. We have to go to the task bar or manager to close out of the client. Normally happens after playing a game or two in Normal New Draft, haven't tried after a Ranked game. It's not game breaking, just inconvenient.

1 ) Start client up as normal.

2 ) Play at least 1 game on Normal New Draft.

3 ) After game end screen, click Home.

4 ) Try to close after going back to Home Screen.

Not really sure what else there is to say, just thought I'd let you guys know. Appreciate everything you guys do!
