I just saw this.
I don't know @DivingDuck, the nozzle should not be re-extruding where it's already been. This looks like it might be a bug.
I don't understand the pattern though. It's lightning infill but that outer area makes it look like concentric.
@rat_tech I know some time has passed but could you load that model, re-create your Cura settings, and then use the "File |Save Project" command and post the 3mf file here? It may provide a clue as to what is going on.

PETG with 225°C is quite low. No wonder that your extruder skips. Is this really the manufacturer recommendation?
PETG is usually in a range form 230 to 250 °C. Try the middle of what the manufacturer recommend, this is usually a good starting point.
