Who broke my slicer?
Have the Prusa Slicer setting changed, or have I messed something up? I print thin-walled boxes for game components with an internal fillet to round out the bottom. When my printer gets to near a 0.8mm wall thickness I now get this ugly ridge (it's at a different height for different boxes). I pretty much use default settings and my filament hasn't changed, so I'm not sure how this started happening (I can't see anything weird in the slicer preview). I have upgraded firmware and slicer settings a few times, but I can't isolate what caused this problem.

Fat perimeters are pretty normal, especially when you have changes in print times at certain layers. Look for the filament cool down settings. There is a 20 second limit that can be changed to a more reasonable 5 or even 2 second cool down that can help prevent speed related surface defects.
But this setting has always been there, so it isn't a slicer change.

Hardware default settings within the slicer have changed over time, so it's not impossible that settings have changed on you. Try simply slowing down the print with the front knob. We spent a lot of time on this last year, and slowing down external perimeters to 25mm/s was the fix for me. Wall thickness and number of external perimeters plays into this. Thicker walls are less susceptible to the problem. It's also well worth calibrating your extrusion multiplier for each filament. The cumulative effects of variations in extrusion can cause these external surface defects when internal features of a print change.
