hg: lanai/lanai: 8230958: AA Geometry rendering is not supported in metal

[Alexey Ushakov]

Thanks for reporting this. The work is in progress (though the case you’ve mentioned is not reproducible on my dev environment).

Anyway I’ll try to figure out what’s wrong and fix it ASAP.

Best Regards,
Alexey
