On my Raspeberry PI 3 with kodi 9.2.0, the picture flickers like crazy when moving from one photo to the next.
It just quickly alternates between display of the overview page containing all photos and the next photo, and the eventually settles on the photo after a second or so.
It seems to happen with all skins that I tried.
Thanks,
Alain
