It looks like it’s happening at about the area of steepest overhang. Is it possible the bead of filament is not grabbing onto the previous layer and dragging/sagging?

Maybe try slowing down the print speed a bit and/or increasing fan speed.

I’d think it’s the overhangs as well. Try reducing layer height or increasing extrusion width. The ratio of those determines the max overhang angle.

It’s definitely sagging, this happened as I was composing the OP:

That’s the worst I’ve seen, usually it’s like the original picture… Oh damn I just noticed it happens at the same layer heights every time.

Hmmm, so why would this filament give me trouble and not the other one?

  I second callcc’s suggestions. I don’t think it’s a slicer or hardware issue, just optimizing your print parameters for the filament.

Yeah, looking at the suggested print settings for vase mode makes me think I’ll need to mess with the temp and speed. I kept them mostly the same as my non vase mode profile which is probably is the issue.
