The other day I was pair programming with a co-worker and the screen got really blurry several times. A question came up--whose internet network was having issues, mine or his? It would have been nice if one of us would have gotten a warning or some other indicator that our network was having issues, so the other person didn't have to try to change their settings as well. For instance, I use a VPN, and would like to know if turning it off would help, or if it's really a different issue altogether.
