WebP - processing error in Safari

[jashsayani]

Describe the bug
When I try encoding or decoding using the WebP format in Safari, I see a "Processing error".

To Reproduce
Steps to reproduce the behavior:

1. Go to https://squoosh.app/
2. Click on "Large photo"
3. On the right, pick "WebP" in dropdown menu to compress
4. See "Processing error" shown on bottom of the page

Version:

• OS: macOS Catalina 10.15 (19A602)
• Browser: Safari 13.0.2 (15608.2.30.1.1)

Given this only happens with the large photo, and only affects decoding, I'm 80% sure this is a memory issue.

@surma any thoughts? Do we just need to give wasm more memory?

This bug is still reproducible, btw o_O

I don't see it on the same photo 🤔

Ah, is it Safari-specific? Unfortunately I don't have access to a Safari I could test on, but I might try via Browserstack at some point.

Yeah it’s only Safari for some reason

Very interesting. Is there something in the console?

(FWIW this is one of those cases where Sentry integration can help us a lot in future)
