I'm not 100% sure but I think the stutter happens even with Vsync OFF on Mac. But because there is a lot of screen tearing it's harder to see the stutter. Turning Vsync ON helps the stutter to be more visible.

This is a critical issue! It's not possible to release anything on MacOS as long as this remains unresolved.
Please advise any workarounds that can be applied locally.
