Scrolling the screen on mobile is very laggy, and then the screen flickers for a moment and attached image's canvas area is crashing(?)

I'm using Pixel 5 and Chrome 122.0.6261.105

I can see this message in console.
WebGL: CONTEXT_LOST_WEBGL: loseContext: context lost

and I did some research.
Reducing width and height of this will reduce lag, but will change the look...

const { devicePixelRatio = 1 } = window
const { width: w, height: h } = canvas.getBoundingClientRect()
const width = w * devicePixelRatio * 2
const height = h * devicePixelRatio * 2
const size = 0.1
globe = createGlobe(canvas, {
devicePixelRatio,
width,
height,
phi,
