maplibre-gl-native v6.0.0 breaks on raster rendering on Apple Silicone

[boonboonsiri]

maplibre-gl-native v6.0.0 introduced changes to use Metal GPU rendering on macOS. However, for generating static tiles, the tile server will eventually freeze.

The easiest way to notice this is clone an empty tileserver gl repo and scroll around the raster tiles for a little. Notice that the server evetually freezes

git clone https://github.com/maptiler/tileserver-gl.git
cd tileserver-gl
npm i
node .

Click on raster tile

I have confirmed this issue on a M2 mac.

Like I mentioned in the slack thread I made a minimal application at
https://github.com/acalcutt/maplibre-node-test/tree/macos_test

The test application is just supposed to generate 50 images. On windows this works, but on macos it freezes after 32 images. I think this confirms it is a maplibre-native issue, but I am not really sure how we will troubleshoot this there.
