Check the whole path of the filament, or maybe rotate the part before printing. Sometimes a combination of factors can cause just enough friction to under-extrude in just parts of a print. I sometimes get it when the filament roll rubs on the holder. This looks like it could be that it’s doing a fast bit while twisting the Bowden tube.
What’s even more annoying is when their refinements end up putting an objectively wrong answer as the authoritative record.
I found a question where someone new to electronics was how to get more current from a USB power supply.
The “correct” answer that was posted before the question was closed was that a source can’t limit current and the questioner should learn more about electricity.
The actual correct answer - and probably what the questioner was looking for - is to short the data lines together because a compliant USB charger will only supply 500mA by default, not it’s stated max current.
