Hi all,
I got this error in Safari 15 for https://deck.gl/examples/geojson-layer-polygons/
WebGL: INVALID_OPERATION: useProgram: program not valid
It was working in older version and in other browser though. I initially thought it was a Deckgl bug but seems like Safari 15 is having trouble with WebGL in general as this demo doesn't work either http://webglsamples.org/blob/blob.html
