If you zoom in real close you can see some purple pixels in the image, maybe both lines render on top of each other and not odd-even.

I noticed this too today when selecting railways.

This happens when the start node of the way is out of the mapview.

Is this new? It seems to be a problem with clamping. And the clamping code is several months old, so we might have this issue for quite some time now.

[Klumbumbus]

regression somewhere between 12389 and 12400 (maybe r12399?)

[bastiK]

Probably collateral damage of [12399]. Michael, could you have a look? Ideally the repeat-image-phase and the dashes-background feature should both work at the same time.

[michael2402]

I'll have a look at it the next days. Should not be hard, probably some sign issue.

In 12448/josm:

extend test case for MapCSSRendererTest (see #14980)

[Klumbumbus]

I think we should release a hotfix for this. Railways look strange (only white stripes and the selection is nearly invisible) and their start node is most of the time out of the mapview as railways are often long ways.

In 12450/josm:

revert [12399], fixes #14980, reopens #14926

[Don-vip]

r12450 released as hotfix.
