Map drawing problems when zooming
I am having problems with maps being drawn incomplete when zooming or panning the map. Parts of the map are drawn, parts are not drawn, and some parts only the altitude shadows are drawn. And one time some of the tiles showed a text which translates into "unknown problem".
Switching map does not solve the problem, as one of the video's shows.
I am using offline maps from Locus Map, Freizeitkarte and OpenAndroMaps. They all show the same behaviour. I have attached some screenshots and video's.
