Expected results: Expect to have seen black instead of red and blue. A picture/screenshot is worth a thousand words and is attached.

You should be able to do that by setting gfx.webrender.all=true and unsetting gfx.webrender .force-disabled. I expect this will improve performance, battery life and remove the artifacts.

I am running the "bleeding edge stable" of the Panfrost driver with OpenGL 3.3 enabled (I believe the latter part specifically is experimental); no idea if that has any bearing on this but I'll disable that later and see if that makes any difference. Appreciate the suggestions (and possible hints at improved power consumpiton in the future on aarch64/in general by default). Cheers, and again if there's anything else I can test I'd be happy to help.

They're probably worth > reporting to upstream mesa. They could be panfrost issues but then we need to explain why the the previous version of Firefox is working fine with the same panfrost drivers. In addition I have two ARM Linux systems. One is 18.04 LTS X11 the other is 20.04 PANFROST. So whether there is panfrost or not the problem still exists. I think we can safely discount PANFROST at this time.

I could reproduce the problem with sw-wr on ARM64 Win10. Then it seems arm specific problem.
