I see a weird rendering problem: scrub is rendered correctly, or incorrectly “under” another green area with just the bushes drawn over it. In this case a big scrub is drawn under a meadow and over a grassland. There are 2 other smaller scrubs visible and drawn over everything as expected (those I’ve added more recently).
Is this a bug?
Is there some kind of hidden layers position?
Hm, can a meadow and scrub/forest occupy the same location? I’m not sure about the exact definition of the tags. But if the mapping is correct, you might want to report this as an issue with openstreetmap-carto, the style definition that is used for the standard map layer on osm.org.
