Attachment: Reftest log on arm64 mac

Bug 1682715 was filed about Software webrender being broken on arm64 windows, and disabled it entirely on arm64.

Since then, it has been determined that it's also broken on arm64 mac, and that some webrender reftests are failing on arm64 mac too (when running wrench with --software reftest). I'm attaching the reftest log. Looking through reftest analyzer, some of the failures match the kind of brokenness I was seeing in Firefox (like rounded-rects).

This could actually be a dupe of bug 1661946.

This could actually be a dupe of bug 1661946.

Maybe it's not, there are way less errors running the reftest on arm64 linux on graviton.
