Certain street labels (e.g. A7 in the top right of this screenshot here) are sometimes cut off between tiles (this also happens after clearing the cache, and when requesting the images through the API directly). If I can, I’d like to report this to the developers. Can anyone tell me where to report this bug, and bugs like this in the future?
Can reproduce on standard Carto: OpenStreetMap
The OpenStreetMap Carto - OpenStreetMap Wiki style is maintained at GitHub - gravitystorm/openstreetmap-carto: A general-purpose OpenStreetMap mapnik style, in CartoCSS.
This issue happens a lot at tile boundaries. If you refresh, you can see that the label crosses such a tile boundary. I don’t know who exactly would be responsible for that, but it also happens with CycleOSM (the 7 is cut off at the exact same spot): OpenStreetMap
Yes, this is a known issue/feature of raster tile rendering.
I suspect that this issue isn’t related to the map style. The OSM Carto map is written in CartoCSS, which in turn uses Mapnik, and that looks like a Mapnik effect. Solving problems there is way above my pay grade (but a look at the contributors may show some familar names).
Here is a similar problem in a different style. Clicking the “vector” button at the top of that example screen shows the same area in a non-Mapnik renderer that uses different display technology, and the problem does not occur there.
