@robmoz are you also facing this issue? I tested again today and now `drawImage` is just throwing an API error for Windows Machines.

No I’m not. Just trying to help.

Sounds like an the flickering sounds like an API bug which needs to be fixed.

@robmoz appreciate the support! I think the `drawImage` API is fully broken for Windows now haha. I’ll open up a new ticket and am attending office hours today.
