ParticleLayer rendering on Chrome on Pixel 10 Pro causes WebGL to crash

[jfred]

A simple deck.gl instance with a WeatherLayers.ParticleLayer added crashes WebGL on Pixel 10 Pro Chrome.

Expect the long term fix will require a change in Chrome, and have submitted the issue there, but looking for any possible alternative mitigations in the short term.

Steps

1. On Pixel 10 Pro Chrome
2. Visit pen that: https://codepen.io/jfred-the-looper/pen/vENvPpq
   • Creates deck.gl instance
   • Adds WeatherLayers.ParticleLayer when "Show Layer" button presses (random data)
3. Click "Show Layer"

Happens on Pixel 10 Pro chrome stable, beta and webview

There is a progress in Chrome issue. This was a good idea to post there. The crash is happening when calling WebGL2 function glCopyBufferSubData, used by luma.gl here.

WeatherLayers Particle layer uses two state buffers for aging particles by copying the buffer content with offset here. A crash due to a memory usage is surprising, because the buffers are pre-allocated.

From the discussion it doesn’t seem there could be a way to prevent the issue from application side yet when glCopyBufferSubData is needed. Let’s see if it’s confirmed to require a Chrome fix.
