Under extrusion after printing overhangs

I've noticed that after printing an overhang, I get a pretty noticeable under extrusion line.  The object I printed below was printed in the orientation shown,

 

I've calibrated my extrusion multiplier and linear advanced.  I've messed around with various overhang speeds from 10-25 mm/s (with "detect bridge perimeters" on) and also saw no improvement.  I've performed a cold pull and everything is clean.  Anyone got any ideas how to fix this?  

Here's the part to look over my print settings: Overhang test

Kind regards

I've tried a lot of things and unfortunately couldn't find a fix to it.  The under extruded lines are really only visible under certain lighting at certain angles, so I could get away with it.  It was just something I noticed and wanted to see if there was any way to resolve it.

Same for me so far. What is strange, that I can find the lines also on other objects on the same hight if I print multiple objects on the same print bed. Today I contacted the Bambu Lab support. Lets see what they say. I will keep you updated.

Hi, I tried the last couple of weeks to solve the issue. Sadly with no success. I posted my experiece with the company and the seller on the trustpilot page if you are interested.
