Unusual high spot on top surface even with very low flow ratio

My prints top surface has unusual high spot even though i have reduced the top flow ratio to 0.65 I could not figure out what is causing this.

This only happens to my black PLA for some reason, if i did it with any other color (same settings) the high spots are not there. I noticed that it apears near the walls. I know that i need to create a special settings for black but i have no idea what setting causes this, its definitly not flow ratio as i set it very low, any lower the top layer will not stick anymore

Any idea what this could be?
