class BugReportExample extends React.Component {
render() {
return (
<MapView style={{ flex: 1 }}>
<MapboxGL.RasterSource
id="wms-source"
tileUrlTemplates={[

Observed behavior and steps to reproduce
- When I add a raster layer to my map, the layer loads but the layer behaves weirdly, randomly loads and then the tiles disappear and appear again randomly, and the tiles loading is also random. Take a look at the attached video.
- The issue happens when the map is idle (not interacted with), zoomed in or being panned.

Expected behavior
- The layer should load gradually like the other layers, and once loaded, the tiles shouldn't just randomly disappear.
Notes / preliminary analysis
- I am loading geology layers for all states of Australia. The rest of the states load fine, only the Queensland causes issue. The same layer loads fine on web too. Here are the rest of the tile urls for reference:
- South Australia
- New South Wales

Research direction
The issue includes a standalone React Native example using MapboxGL.RasterSource and RasterLayer; start by running it on Android with the Queensland URL and observe loading while idle, zooming, and panning. Compare it with the other supplied raster URLs; done means Queensland raster tiles load gradually and remain visible without randomly disappearing.
