Poor surface quality when sweep interrupted
It looks to me like you have underextrusion in these regions probably due to loss (oozing) of material during travel moves prior to printing them. Aside from small gaps in the surface sweep at the part you're talking about, I see a long slightly-diagonal light-gray line between the middle of the right and the middle of the bottom of your image, which appears to be material that oozed during combing.

Make sure you have retraction enabled, have sufficient retraction (at least 6 mm for bowden; somewhat less for direct-drive) and either disable combining or set max combing distance very small (like 1.5x nozzle width) and see if this helps.
