[Under-extrusion at start of some lines]

After extensive research this post seemed to describe the problem I was having the best: 5-10mm of some but not all single width line segments were underextruded as shown after a travel move, and none of the settings that would logically fix the issue really addressed it properly. My model also has several single walled features which would be consistent with the OP's hypothesis of cura not slicing properly when switching between different width thin features. After a large amount of time playing with every setting that could remotely have anything to do with outer perimeters, I found that disabling the "Compensate outer wall overlaps" setting made the single wall extrusions behave as intended. Phew! Hopefully that helps anyone else who is seeing this issue. I don't know why this setting would change the way a single wall feature is extruded. I'm inclined to think it is a bug.

Thank you for sharing this, in my case I disabled both inner and outer wall. Solved a problem I had been battling for days now!
