When in a game on steam, about half the mouse clicks do not register. This issue doesn't seem to happen in any other applications that i've tried or on the steam client itself.
The issue started when I used bettertouchtool to try and remap a few of the extra buttons on my 3rd party mouse to different keys. However now even when bettertouchtool is not running the issue still happens. I've tried using a different mouse, the trackpad on my macbook, and an apple magic mouse and all of them have the same issue. As far as i know this happens in every game in my library.
