[iOS] App crashes on relaunch, metal shader related

[danielduan]

This seems to occur on about 5-10% of users out in the wild so it isn't an isolated instance. It happens after the app has been closed and backgrounded, and then reopened. I don't have a precise sequence to replicate but I have encountered it myself on production builds and I have the stack traces from Crashlytics below.

The app is a standard Expo 54 project with the ConfettiProvider at the root _layout.tsx and the actual useConfetti in a separate screen. The confetti is the only use of WebGPU.

"react-native-wgpu": "^0.5.11"
"typegpu-confetti": "^0.2.0"

Thanks for the bug report, and for the thorough context! I'll try to reproduce the bug locally and get back to you, I might have an idea on how to approach fixing this

No problem, let me know if you would like me to validate a potential fix too. I think this might be an issue on Android too.

It looks like the WebGPU Canvas might need to be unmounted when the app is backgrounded to free up all the GPU resources.

[iwoplaza]

I just released typegpu-confetti v0.3.0, which builds on top of the new @typegpu/react package. It's a lot more stable in testing, the only errors I saw in use happens when dozens of canvases were overlapping on top of one another. This seems to be a react-native-wgpu stability issue. We'll try to help William (the maintainer of react-native-wgpu) resolve this issue upstream.

For the time being, I would love to know if v0.3.0 fixes the issues your users have been experiencing

[danielduan]

I just updated the package and it seems to have fixed the issue from my own testing. I will create a new release and report back if I see anything from Crashlytics.

[danielduan]

I just got a crash report on Android with the new version on a SM-A176B device
