Behavior

Excessive travel when printing gap fill infill
I sliced and printed a part today and noticed that while doing gap fill on the edges there is excessive travel. Not just inefficient, as referenced in #1934, but it is hopping back and forth to a corner point where there is no actual extrusion necessary (or happening - observe the extruder visualizer in the video). I have attached the G-code produced and 3mf file. Turning on 'travel' in the preview shows the travel moves as well.

There is also a video of the problem. It starts around 20 second in after the perimeters are done.

No
