Yes - it's a confusing title - but please have a look at the picture below.
This happens to me after 5 seconds or so of using TV to access a customer's remote computer. Of note is the fact that the screen will not go like this until I start doing things on the client's computer (if I just connect and leave it - it's fine).
This particular client is using Teamviewer 7 Quick Support (they have other IT that insist on using V7 while our organisation uses V13)
Sometimes the connection recovers from this condition itself. I have updated my video drivers already - to no avail.
I have v13.0.6447. I never had this problem when we were using Teamviewer 8. Any help would be greatly appreciated.
