with CRF 18-22 in 1.0 steps.

CRF 18 results in 5.1Mbit/s (the original has 37Mbit), but all still have the same issue.

Anything else that can help?
Obviously otherwise only using very high bitrate might solve this or not re-encoing at all or accepting that this might happen.
Perhaps stick with the default Aq strength for the time being. CRF 18 with Aq mode 3 really should look good.

I take it you're running the latest build?

In the interest of narrowing the problem down, maybe try the "slower" preset. I'd also see if --qg-size 64 can help and there's always good old Aq-mode 1.

Is the source very grainy?
