[CLIENT BUG] After a few games, lobby screen goes black

So this has been happening to me recently. after playing a few games, sometimes as little as 2 games. When you finish a game and go to play another you can't because the lobby screen is black with no way to exit it or do anything, so you cannot hit play. The only way i can fix it is by closing the game and re-logging. This fixes it immediately, but the problem doesn't go away, as it will happen again after some games, resulting in me re-logging multiple times a day to be able to play.

I should note, that it is only the lobby/play screen that is black. Everything else, like the loot menu, store, profile is fine.

It is getting incredibly annoying.
