I have just noticed an interesting thing: Solid infills have preset one of the highest print speeds (160mm/s), whereas bridges have one of the lowest (15mm/s). Even though the solid infills are basically bridges. How so? Is it deemed, that they wont be visible, so they can print rubbish? which is questionable, since they ultimately support outside features...

What are your experience with this?

Here is an example. see on the left: what is next to the outside 2 perimeters PrusaSlicer considers Solid infill and prints absolute rubbish... (with lot of unhealthy noises as the nozzle goes across bumpy layers).

Maybe it should be split in 2 settings: Solid infill (fast) and inner overhang (slow)?

This is from PrusaSlicer 2.9.0
