No so fast. The problem persists, at least for me. Yesterday, on a Zwift ride, my Zwift was running full screen, All of my screen shots were black blanks. Today, under identical circumstance with Zwift again running full screen, all of my screen shots were good. I have noticed this problem come and go rather randomly over the last six months. I works more often than not, by the way. I ride everyday and I note each time it screen shots don’t work. The occurrence of the problem seems unpredictable. I am using Zwift Companion with Zwift on the laptop.
