@sdetweil That’s it! That’s it! Thank you very much! I find it strange that the module ran for weeks with this setting. And suddenly no more.

I had to rebuild my entire MM that the SD was broken. Now there is the following problem: Whenever the picture in the module MMM-GooglePhotos changes, the whole screen is black for a short time and then rebuilt. This was not the case with my first installation. There the picture changed without the screen renewing itself. How can I fix it?
