it occurs every 30 mins. I use Unity 2017.1.1f1. It is a very annoying bug, why don't you fix it?

Still occurring in 2017.1.1f1 (9/4/2017 release). I understand a fix is coming in 2017.2 (and is fixed in the current Beta). Just posting this for anyone else who'd hoped that the latest release had solved the problem...

I just installed Unity today version 2017.1.0p5. I have started watching some tutorials on the site and going through them and appears this happens randomly anytime I alt tab between Unity and Visual Studio. It can happen every 30 minutes to as soon as I start Unity back up and alt tab for the first time.
