Could it be related to the recent update (https://github.com/maplibre/maplibre-native/pull/2443)?

[louwers]

@agurbovich-lyft Thanks for the report. Are you using raster tiles?

[bsudekum]

@louwers we do add raster layers via MLNRasterStyleLayer. The style at run time does not contain raster sources.

[bsudekum]

@TimSylvester do you think this could be related to https://github.com/maplibre/maplibre-native/pull/2443?

[TimSylvester]

I don't see how, but I can't rule it out.

Any thoughts on reproducing this? It came up during our meeting.
