Tilemaker generation versus tile rendering

[BenOnTrack]

First of all, I'm sorry in advance as I'm not sure if my issue lies in my tilemaker config or in my maplibre-gl setup. I've decided to start asking here as I found the tilemaker community very re-active.

Issue
I have a map instance of maplibre-gl, that fetches tiles that have been generated via Tilemaker.
I have POI - cities that are stored in my layer poi. They have a minZoom set to 10 / maxZoom set to 14 in my tilemaker configuration. When the user clicks on a rendered feature (so for instance, when the user "sees" a city POI (rendered as a point) on the map, and clicks on it), the following actions occur:

• I grab the coordinates of the rendered feature (so the coordinates at zoom 10 for instance (depending on which zoom the User is currently when clicking on the map), from the tile generated by Tilemaker)
• and I do a flyTo to zoom 19 (to "bring" the user closer to their clicked POI)
• I then add a maplibre.Marker based on those coordinates.

The issue that I have is that I end up with a maplibre-marker completely off my initial POI coordinates, as you can observe in the picture below:

As mentioned in the Tilemaker documentation, I don't think it's worthwhile to generate tiles beyond zoom level 14. That said, I'm curious to understand what I'm doing wrong and whether the root cause of the issue lies within my Tilemaker or my MapLibre style/config setup.

However, my gut feeling is that beyond zoom level 14, MapLibre GL may be "extrapolating" the coordinates of the last rendered feature (up to zoom 14), which could be causing the distortion in my render.

I've also tried to "change" the maxZoom of the source layer poi and could not find a better solution than setting it to 14 (any value above and the data would not be rendered at all, which is compliant with their documentation on this setting).

I'm using maplibre-gl on a mobile version, and zoom 14 is still very "low" in terms of resolution, hence the reason why I need to zoom up to 19 to really focus the viewport on the POI.

Tilemaker Config
"poi": { "minzoom": 10, "maxzoom": 14 }

Maplibre style
"poi": { "type": "vector", "tiles": ["japan/{z}/{x}/{y}.pbf"], "maxzoom": 14, "promoteId": "id" },

{ "id": "poi", "type": "symbol", "source": "poi", "source-layer": "poi", "minzoom": 10, "layout": { "icon-size": 1, "text-anchor": "top", "text-field": "{name}", "text-font": [ "case", [ "==", ["get", "class"], "place" ], [ "literal", ["Noto Sans Bold"] ], [ "literal", ["Noto Sans Regular"] ] ], "text-offset": [0, 1], "text-max-width": 9, "text-optional": true, "text-allow-overlap": false, "paint": { "text-color": "#666", "text-halo-blur": 0.5, "text-halo-color": "#ffffff", "text-halo-width": 2 } },

I wonder if the issue here is #771. Assuming you're using the latest source, if you set "combine_points": false on the layer then does it do what it should?

Thank you for your feedback.
I've installed the new tilemaker version, updated my config.json to include the "combine_points" : false but unfortunately I still see the same behavior.

mapFeatureCoordinates 139.75313186645508,35.693831121450316 for zoom 10.496414441800132
mapFeatureCoordinates 139.75317478179932,35.693831121450316 for zoom 11.333683540781562
mapFeatureCoordinates 139.75319623947144,35.69381369467831 for zoom 12.500182757857127
mapFeatureCoordinates 139.75321233272552,35.69381369467831 for zoom 19

I've started to log out the long/lat of my queryRenderedFeature at different zoom, and I can't really figure out a pattern that would match any of my config, tilemaker or maplibre-gl.

One workaround I'm thinking of, is to:

• first flyTo zoom 19
• perform a second queryRenderedFeature within a Bbox around the initial point, and check on the feature.id
• fetch its coordinates
• generate the marker only at that point.
  It's not really clean, and also when zooming out it might be obvious that the marker is offset from the point, but it might still be my best best. (just would still love to understand what is generating this offset :-)

Could you put the pages and tiles somewhere public so I can take a look?
