G4 pauses in 4a Low Quality profile

[cyclone 0]

I've noticed that the infill produced from NF 4.9 using the 4a Low Quality profile / material adds a bunch of G4 P10 and G4 P60 lines.

Does anyone know why that is? It prints fine but the machine runs and then quickly stops and hesitates a lot during a print. I'd like for it not to do that. The point of LQ is to print faster, or so I thought.

I've looked at the words in the Build Style dialog and even compared them with the words in a non-G4 adding style and it seems like there is no "add a pause for no good reason" checkbox that I can uncheck.

After a bit more time looking at the gcode the G4's seem to be around non-existent filament retraction code.

If you go in and put a value > 0 in the RPM for Push On and Pull Off it adds several lines of code with the G4's.

Is there a way to not put these if the RPM for retraction is 0? Removing the G4's removes the strange pausing

behavior (obviously).

I really think this is new behavior with the last update.
