Most of the time when I open the steam overlay, the game stops working. Not visually, the game doesn't freeze, but no buttons work. I cannot press anything, the only thing I can do is to open and close the steam overlay. This forces me to alt-tab out and close it from the taskbar, and this can be really annoying as I often open the steam overlay in the beginning of matches. Sometimes spam-opening and closing the steam overlay fixes it, but most of the time, it doesn't. I am not sure if I am the only one having this issue, but it is really annoying.
