This has been happening since the most recent patch update (7.1). Whenever I play in full screen mode, my game will randomly alt tab out on its own and I don't know how to fix it? Is anyone else having this issue on the Mac client? I play on a macbook air, so playing windowed kinda sucks.

Lucie Lovelace1 votesI actually figured it out! (I think). The new league client interferes with any screen saver hot corners you have set. For me it was my lower left corner, and after a few tests of scrolling my cursor over there in full screen mid game, I decided thats what it was.
