Are these Surfel GI artefacts?

There are blocky artefacts around the edges of geometry with Surfel GI. Some are more noticeable than others.
Is this expected behaviour?

That's odd, I don't have this kind of issue, maybe it's something GPU dependent.

I do have an AMD card, so maybe it could be dependent on that

Reminds me of the kind of artefacts you see when doing non uniform texture sampling on AMD
