Dissolving support weird slicing issue
printing a faceplate for the amazing 737diysim FMC (working 737-800 flight management computer for MS flight sim) see here
Anyway the issue is seen below, on the round keys (numeric) the slicer did full support (all the openings are overhangs to retain the keys/screens) but on the square keys (letters) you get the side towards us a wall of full support and the opposite as seen gets a little post of support. If it was one or two keys, I’d assume the BVOH fell or something but all 26 being identical makes it intentional. As it turns out the little pillars kept the overhang pristine, so while possible to guess that prusaslicer did this deliberately, since the keys are perfectly square no reason to do one side as full support. The weird thing is the corner supports are much, much harder to dissolve (after soaking 30 mins my toothpick broke scraping it off). I can’t distribute the model under the license (but the build guide above has links to Karl’s site) this is my first FDM build of this part as resin feels better, but was too low on gray to kick it off.
prusament recycled pla (don’t worry it gets a hit with the Boeing gray) in extruder 4
matterhackers BVOH in extruder 2
both using stock profiles, both spent the night in the filament dryer (it is a dreary rainy fall), 0.15 structural, supports everywhere (way to many surfaces to hit by hand!)
satin sheet (best sheet in my opinion) freshly cleaned

RE: Dissolving support weird slicing issue
Not weird at all. Stock profiles usually have 'Don't Support Bridges' enabled. As long as there's connection at each end it will try and bridge the distance in between. If you examine your sliced print preview you would probably find those areas are keyed as dark blue. If you had attached a PS project file we could check but my money is on the don't support bridges setting.
This is why carefully checking the preview options and stepping through layers before printing is an important habit to acquire. Sometimes it tries to do bridges that are far longer than it can do so you need to check.
Also re: the comment about using auto as there's far too many spots to do by hand, have you tried the support painting tool option for auto painting? Its surprisingly good and its easy to then use it as a basis and modify the areas with the human touch.
