line pattern not scaling consistently

[dieterdreist]

I set a line pattern via sprite and it works well in the js preview in the browser, but on iOS retina the pattern is distorted / cut and looking very differently. Is this a known issue? I found something in the Mapbox repository about this problem, for example here mapbox/mapbox-gl-native#16359

@dieterdreist Can you provide a reproduction?

I just updated and I can confirm it still exists.
Here is a test style with sprites and tiles to test around 12.51E / 41.85N

Could you try out the Metal pre-release: #1609 ?

I didn't manage to use the prerelease, but with the current 6.3.1 the problem is still there, but it is looking differently.

Here screenshots from the same area:
