Minimizing League (while in-game or loading screen) causes guaranteed bugsplat.

I've had this problem since the newest patch. Every time I Alt+tab to minimize League in the loading screen or in-game it will bugsplat 100% of the time. It takes a really long time for the client to load the reconnect button afterwards making it so I barely reconnect before 3 minutes. This bug almost forces me to watch the entire loading screen. Sometimes it won't let me alt+tab while in-game and sometimes it does let me, that part's random. Shouldn't be hard to recreate unless it's just affecting me.
