I think you may have linked the wrong ticket, that one is about the fonts in cura 3.2...
Concentric Infill has similar effects, but not so bad. The infill percentage doesn't change this until it is 0%, in which case there is no fill.
Wall thickness option seems to have no effect. The issue is caused by having a part that is thinner than 2x total wall width, but thicker than 1 line of the wall so it does this strange infill pattern.
Attached is with concentric infill, then changing the wall width to be less, concentric infill. It seems to be a worse issue with the gyroid infill.
Minimum infill area is the only setting that I could see affecting it.
