Mitigate wall bulge
Ok let me share my progress!
I've modified a lot of settings, I increased the wall thickness to match my line width and the results were a bit better but never close to what I get with Cura.... well, I read on one of the posts about Super Slicer 🙂
I'll just leave it there..... This IS a Prusa Slicer problem.
I'm so happy I found this thread and the others you all mentioned. I've been having an issue where a solid layer begins 42 layers up a print to form the base of a jewelry stand and at the same layer number a couple layers of what appears to be an extra external perimeter is printed for a couple of layers and then it disappears. It has been driving me nuts because I haven't been able to solve it.
Now I know what it is called, possible fixes, and possible alternatives (cura). Thank you everyone!
