Euston Road London rendered weirdly in dark mode

[peternewman]

As title. Needs more investigation.

It looks like a river almost semitransparent blue.

It seems to apply to highway=trunk and highway=motorway but not highway=motorway_link.

They look fine in the light mode.

To me, switching to blend: translucent in lines-highway-style looks better, then optionally making the highway_color have some transparency.

It looks weird also to me:

Note, railways suffer from similar overlaps but far less severe ones.

Even though this is kind of a bug in tangram-es, i think it looks quite cool

The longer overlap or the dots? It just seems a bit odd to me as it potentially has no or limited relevance to the road (e.g. change in lanes causing a dot).

For me it looks quite glitchy/confusing but also cool.

One part of the bug is caused by

https://tangrams.readthedocs.io/en/main/Syntax-Reference/draw/#cap

(cap: round)

tangram-es draws a round cap for each segment of a way, so at the point where there are two consecutive segments, two opposing round caps that complement each other become a circle.

Looks less cool, but also a lot less weird/confusing when removing

streetcomplete-mapstyle/streetcomplete-dark-style.yaml

Lines 46 to 51 in 2ecce80

	lines-highway-style:
	base: lines
	blend: add
	lines-railway-style:
	base: lines
	blend: add

Very simple to test in https://streetcomplete.github.io/streetcomplete-mapstyle/?provider=jawg
The colors might then need some adjustment...
