I've been having this problem when every few photos, just a plain green picture is taken. And sometimes there are distorted colors. I decided to play around with the settings to check if it changes anything.
I found out that the problem is keeping the focus mode in Continuous Auto focus. Keeping it in this mode apparently has problems which are the green photos, distorted colors, and around 2 seconds of lag between the shutter and the photo being taken.
Keeping it on Auto took off 2 of the problems which were the green photos and distorted colors. But it was still kind of laggy, I think it's supposed to be this way though to have time for it to focus
Putting it on Infinity fixed all of it, I took over 20 photos without any problem or lag.
I don't know why that problem occurred, but it's probably just the camera firmware and not a hardware problem.
Hope I got to help
