Hello Pzaz,
I am sorry you are having issues with your Moverios and Mavic. We have not had reports of this issue on the latest Go4 available from the Moverio Market. One common error, which I am guilty of, is allowing multiple instances of the Go4 app run in the background at the same time. Please be sure to exit any apps that may be open as G04 is very resource intensive.
FWIW, it’s been working fine for me. Make sure you’ve got enough light when you’re testing- low light can result in pixelation as well.
