Come to think of it, since I swapped around my USB posts, including moving the camera to a 2.0 from a 3.0, I haven't had any tracking camera crashes.I don't know if you've tried this already, but I had a similar issue with my setup. I found that moving the tracking camera connector from a USB3 port to a USB2 port stopped the flashing for me. I think this might have been posted elsewhere on this forum.
Forgot I had done this until I read this post.
Give it a try.

It would be nice if there was a setting that disabled the color change associated with tracking loss. I've found that the game runs much smoother if the tracking camera is disabled, and it tracks head motion nearly as well. The only thing you lose is the ability to 'lean in', but since changing the HUD to green the text is much more legible, and I wouldn't miss that feature either.
