Game Window Configuration won't stay

Ever since patch 3.3 came out, my game window/screen mode will not stay the way I configured. The options says it's "Borderless Windowed", but each time I open the game, the game is "Windowed". It's just a small thing, but it's bugging me a lot since it means I have to re-set the screen mode each time I open the game.
Everything else, as far as I know, is the same and hasn't been affected.


Date & Time:
Any day, any time I open the game after Patch 3.3

Always

Siren (since that's where I play most of the time. But since it's a whole game-window related, I'm sure the world doesn't matter)
