There are several issues here -

• From what I see in https://github.com/bobcob7/wasm-rotating-cube/blob/master/bundle.go#L87, there are several typed arrays which are never released.
• And I believe (I could be wrong) that if you just reload the tab without closing the tab, or doing a clean exit from the app, the app does not shut down cleanly. Which means that any held resources are not released. And from the code, I don't see the app allowing the user to exit from main(). https://github.com/bobcob7/wasm-rotating-cube/blob/master/bundle.go#L209. So nothing ever gets released until you close the tab.

Just discovered this. I think it's a bug in Chrome because I have the same issue with an alternative WebAssembly compiler (after many reloads) and I never had it with Firefox.

If you ask me, all resources should be freed after a page is reloaded. Apparently Chrome doesn't do that (but does after closing/reopening the tab).
