I recently bought a second monitor and I would like to use it for viewing twitch chat and other things. Problem is that whenever I play TF2 it tabs me out of the game whenever I flick too hard and press my left mouse at the same time. I tried using Dual Monitor Tools to lock my cursor on one monitor, but despite that it still happens from time to time and I don't know why. I also tried aligning the second monitor to the top right corner (like this) but that didn't really seem to decrease the likelihood of it happening either. I don't seem to have the issue in other games, haven't tried other Source games as I don't have any others installed.
It's driving me up the wall when I'm fighting someone and my game tabs out and I don't know what else I can try, so I'm looking for advice from people with a dual/multi monitor setup, thanks in advance :D
Other things that might be relevant:
- I'm running TF2 in fullscreen
- Monitors: LG 27GK750F + BenQ XL2411Z
- One of the monitors is in portrait mode
