Hello community,
I am having an issue with my prints on my CR10 recently where I seem to have overextrusion and the print surface gets rough, but only in certain spots.

I have analysed the problem to occur either where two "fronts" meet or where the printer has to make fast direction changes in order to fill the last small spots left in a layer. Its has to be either one or the other of those two. Same with first or last layer it happens on both in the same spots.
What I have tried so far is to lower the esteps which didnt help. I increased the printspeed because I thought maybe the printer extrudes too much when he goes too slow in a small area (which would be a calculation issue then), didnt help. I lowered my printbed a bit, didnt help and I am having the issue also on the top layer like I said. I am using cura right now, if anyone wants to see my settings I can provide those
If anyone has had this issue or maybe has an idea I would be grateful for any help.

Picture for better understanding:

I marked the "fronts" I mentioned earlier
