Uneven extrusion on thin wall

I'm trying to create punchable holes for an electronics box by having round areas in the box of only 0.4mm thickness. While the thicker walls print just fine, these thin walls have extrusion issues as you can see in the attached image. What could be causing these issues?

The material is PETG and I'm using Orbiter 1.5 together with A Dragon HF hotend

I've printed 0.4mm walls in vase mode which are fine, the issue seems to be when I have different wall thickness. I've tuned pressure advance as well a retract which were the first things that came to my mind as causes
