Mapsforge V4 renders super slow - V3 works fine
I've been using maps from openandromaps.org in Locus Pro for a long while, and they were always very good.
A while ago I tried downloading the V4 version, but it was super slow to render in Locus - when panning or zooming. So I went back to V3, which was fast.
Now I see that the last release of V3 is the September 2019 one, and there will be no more, basically forcing me over to V4.
So I tried it again, but it is still very slow, almost unusable to "look around" a trail.
I'm using the Elements theme (from openandromaps) for V4 and the internal "Hike & bike" for V3.
I'm using a quite decent phone (Google Pixel 1), so that shouldn't be a problem.
