Rough wall finish on Fine profile

Having some issues with the surface quality on a print when using the Fine (0.12) profile using a generic PLA profile.
It looks like underextrusion on longer stretches of flat surfaces because it’s broken up by sharper curved details. Is this correct or can someone identify the cause?

I have the exact same issue.
Tried changing it to print outer walls first, no luck.
Only showed up on one side
