Ok, I will try and crash the game a couple of times and come up with the files after each. Also I'm running in borderless specifically because of the known alt+tab instability. I can't remember having alt tab problems with borderless. To add to this, if you have 2 monitors (like me), clicking on the other monitor with a fullscreen game that doesn't constrain your cursor causes it to alt tab, or rather minimize. So I'm not actually alt tabbing, I'm clicking on the other screen while in borderless.
