Problems with gap fill under extrusion possible early nozzle pressure release  

Problems with gap fill under extrusion possible early nozzle pressure release

When the option for 'Detect thin walls' is enabled under printer settings, Prusaslicer tries to slice these 2mm walls in 3 extrusion lines (0.4mm nozzle).  Obviously the wall should ideally be divisible by the extrusion width for best results.

It prints the outer perimeters and then one gap fill line down the middle, however when the gap fill line gets toward the end it begins to under extrude and so you can see the line width isn't enough resulting in the gaps on the bottom right corner and the inner top right corner.

I know Cura has a setting for this and you can adjust at what point to ease off the nozzle pressure but i can't find any settings for that in Prusaslicer.

As it is this is best resolved by ramming two extrusion widths into the gap by unchecking 'detect thin walls'.  This is not how this feature is meant to work surely and i wondered if there was any advice here.
