10 years ago We usually don't use github for issues, but you q is very clear. So, I don't see a big issue here, though I agree according to documentation it should not be dashed. You should take into account that OsmAnd uses simplified rendering style and combines all tunnel/layer tags into 1. Particularly here layer="0" and layer="1" looks more logical, so I would say it is a small map defect for OsmAnd.

10 years ago According to the documentation, it is wrong to tag a way in a cutting as "layer=-1"
http://wiki.openstreetmap.org/wiki/Key:layer
Roads, railways, waterways etc. should not be tagged with a layer just because they are raised up on an embankment or are in a cutting - use embankment http://wiki.openstreetmap.org/wiki/Key:embankment= and cutting http://wiki.openstreetmap.org/wiki/Key:cutting=, respective waterway http://wiki.openstreetmap.org/wiki/Key:waterway=ditch http://wiki.openstreetmap.org/wiki/Tag:waterway%3Dditch for this purpose.

10 years ago Where should bugs be reported ? I looked on osmand.net and in the FAQ but didn't find any specific info. Did you close the github issue but reopen it somewhere else ?
AFAICS, the mapper didn't use "layer=-1" to mean "cutting" or "embankement" (otherwise he'd have tagged different stetches of the road), but just to distinguish which feature (road, bridge, tunnel, etc) is on top of another, which is the correct use of the tag.
He didn't follow best-practice an common idioms (don't tag layer=0 explicitly, tag the shorter of two overlaping ways, tend to use < 0 for tunnels/culverts and > 0 for bridges, etc), but his tagging isn't "wrong", and OSMAnd should render it properly.

10 years ago We have Google Groups from where "master" members repost them to internal bug tracker. But you can find it if you really want to see on googlecode.
OSMAnd renders some features with a dashed style when they have a layer=-1 tag, even if there isn't a tunnel tag or anything indicating that the feature is somehow covered.
Trunk example: http://osm.org/go/esy4UoA1 River example: http://osm.org/go/esyyzX0f0- Layer tag: http://wiki.openstreetmap.org/wiki/Key:layer
While the tagging in those examples is a bit unusual (it's not mine), it isn't wrong (there's no point in changing it unless you're also doing other changes in the area).
