Steps to reproduce:

My Flutter website didn't render today anymore (the buttons under it were still functioning), but it just showed an empty background.
I thought it was a problem with my webApp, but a graph inside Google Merchant Center also has the same problem.

Actual results:

Just saw my default background colour.

Expected results:

It should've rendered

Or do a regression range with mozregression https://mozilla.github.io/mozregression/

I'm on the clock, so I don't have time to reproduce the bug for you, but a test case would be excalidraw.com. This is a free no-login application that now doesn't work on Firefox anymore, but it does on Chrome.

Flags: needinfo?(ict)

That site works for me in Firefox, so there must be something more specific about your setup that I don't have in order to reproduce or investigate what is going on.

I don't know what that could've been. Because today, the canvas works again for me.
Very weird.

Thank you all for taking this seriously and replying this quickly.
