Expected Behavior
Clear shapes without flickering
Steps to Reproduce
/*
* https://deck.gl/docs/api-reference/layers/bitmap-layer
*/
const {DeckGL, BitmapLayer, COORDINATE_SYSTEM} = deck;
const layer = new BitmapLayer({
id: 'BitmapLayer',
bounds: [-123, 37, -122, 38],
image: 'https://dummyimage.com/3200x3100/000/fff',
textureParameters: {
minFilter: 'nearest',
magFilter: 'nearest'
},
opacity: 0.5,
});
new DeckGL({
mapStyle: 'https://basemaps.cartocdn.com/gl/positron-gl-style/style.json',
initialViewState: {
longitude: -122.4,
latitude: 37.74,
zoom: 11,
maxZoom: 20,
pitch: 30,
bearing: 0
},
controller: true,
layers: [layer]
});
