Is this related to https://github.com/mrdoob/three.js/issues/26765 ? If so, sounds fixed by Three?
We're using a procedural skybox and three reflection probes. Crash appears to happen at random times, sometimes instantly and sometimes after quite a while.

Thanks, I believe I've seen this before and it's not related to spherical harmonics – instead seems to be related to our on-device poster generation in dev mode running out of memory on some devices (I've seen it on older iOS devices).
We'll investigate; in the time being you can disable poster generation in the vite.config.js by adding noPoster: true:
We'll also soon-ish update three.js again, I do think that cubemap readback error should go away then.
Ok, I'll try that. But in dev mode? Maybe I misunderstand here but this happens on production builds.
