With the release of the NVIDIA 560.x drivers, with all the fixes in it for Wayland display server, I was excited to give it a try.   Firstly, when it works, it is amazing, everything looks so sharp/crisp and no screen tearing at all.  But I have 1 issue, and I have not found a problem.  I noticed this issue in 555.x drivers.   I get whole screen flicker, on both displays. 

I was just thinking about the early days of the Internet, when ISDN was too expensive, and DSL wasn't quite available yet.
