調査の方向性

Start with the linked rive-memory-leak reproduction and compare the heap snapshots after repeatedly mounting and unmounting @rive-app/react-canvas. Trace the canvas references retained by the React package in Safari; done means repeated remounts no longer leave extra canvas elements accumulating in memory.

説明

Submission checklist
  • I have confirmed the issue is present in the latest version of @rive-app/react-canvas or @rive-app/react-webgl2 (or the renderer variant I'm using)
  • I have searched the documentation and forums and could not find an answer
  • I have searched existing issues and this is not a duplicate
Description

We are finding instances in our app of dangling references to canvas elements after rive elements have been unmounted. This is causing a growing memory problem that gets worse over time. It's definitely an issue in safari, possibly an issue in chromium based browsers but more difficult to reproduce.

I've created a repo that makes this reproducible - by mounting and un-mounting the rive component about 100 times I end up with two or three extra canvas elements in the memory snapshot. In our actual app with multiple different animations on various routes, we can sometimes see 10s or 100s of canvas elements accruing over time. With large animations this puts a real strain on memory and performance.

Atached are two heap snapshots, one with the single mounted canvas element and one after re-mounting ~100 times
