Screen goes to black and white?!

 During my intervals today (10min ON, 10 min OFF, 3 times) as I neared the end of each interval, the screen got fuzzy, changed to black and white and generally got really distorted looking.  As soon as I got to my “OFF” interval, the colors and clarity returned to normal.

What is going on?

That is a feature within Zwift. Some people like it and some people hate it.

Ok, I guess that’s good news, I thought Zwift was about to crash or something.  I have done a lot of workouts on Zwift and never had this happen before so thought I would ask!
