Thank you for raising the issue and the screenshot.
The current implementation only works with the unpitched map.

https://github.com/mapcomponents/react-map-components-maplibre/blob/main/src/components/MlWmsLoader/MlWmsLoader.tsx#L166

We will have to get tile dimensions as bbox and then determine the pixel position of the click event relative to that bbox to make a valid getfeatureinfo request in this map state.

I am documenting my ideas on solving this here, one of my colleagues will take a look at fixing it.

  1. Use unproject to turn click events x and y into coordinates.
    https://maplibre.org/maplibre-gl-js-docs/api/map/#map#unproject
  2. Use the coordinates from step 1 to as the bbox north-west coordinates and construct the south-east coordinates from that.
  3. Use fixed width and height that matches the aspect ratio of the bbox from step 2. I/Y or X/Y coordinates can be 0,0.
