No clean screenshot?

I took a screenshot today with F10, and I only got the dirty screenshot. Where did the clean one go?

You don’t always get a clean screenshot. I find they’re very random and if there is one it will be in the same place as the dirty one i.e. C:\Users\yourcomputerPictures\Zwift\ on a Windows PC.

My experiences with screen-shots mirror Nigel’s too Jim.

In the past, I’ve typically been able to get one clean screenshot, as long as I took it ahead of Zwift’s automatic screenshot at around 35 minutes. But maybe I’ve been tremendously lucky. 

So, is this a widespread problem, or is the feature working as intended?
