Fullscreen Games Sometimes Decrease Size of League Client [CLIENT]

Whenever I open up games such as Garry's Mod or No More Room In Hell, since neither of those games have a full screen windowed mode, I usually just play on full screen. However, every time I alt+tab or exit the game, the league client has shrunk down to its minimum size, and I have to manually go in to fix it by going into the settings.

STEPS:

1. Open Garry's Mod (or any game like it) with the league client open, on any client size above 1024 x 576
2. alt+tab OR exit game, and look at league client

Unfortunately I have no evidence to back this up, but it's a simple attempt for anyone who has games such as these two to test out. Obviously, this isn't a big issue, I just thought I should bring it to the attention of you guys. Thanks for reading (:
