Hi Orux,
in recent versions mapsforge maps are not properly scaled according to pixel density. I think we had this before in some beta version, now it's in the GP version.
See the screenshots attached - the patterns don't fit anymore, and it renders smaller than it should, so lines and captions are bigger in comparison. The other screenshot is of Cruiser (reference implentation of mapsforge) at the same zoom level.
Best regards,
Tobias
It's now fixed in the latest beta, and setting mapsforge maps to single thread rendering is a workaround for other OruxMaps versions.
