I **don't** reproduce it on a Dell XPS 13 (cpu: Intel Core i7-3537U, graphic card Intel Corporation 3rd Gen (I think it's an HD4000), on a Kubuntu 20.04.

Do you know whether this has always been the case, or whether it's a recent regression? If it's a regression, if you'd be able to run [mozregression ](https://mozilla.github.io/mozregression/quickstart.html) to help us track down what caused it, that would be great!
