Hey Unity WebGL team, ( cc @brendanduncan_u3d )

We’ve noticed that using a particle system causes WebGL builds to break on Safari after a few seconds.

[Error] exception thrown: RuntimeError: Out of bounds memory access (evaluating 'dynCall_v.call(null,func)')

Any support would be greatly appreciated.

Bumping as this issue still exists

Best way to get attention is to submit a bug report and tag the Unity Dev.

Also, good practice is to mention the Unity version you’re using… or else it’s a needle in a haystack search for them. They are literally working on 5 release-streams at a time if not more; 2023.1 alpha, 2022.2 beta, 2022.1 tech stream, 2021 LTS, 2020 LTS…
