I have a part that is 1.2mm thin. It should print as 3 lines as in Cura 3.4.1. In Cura 3.5 it print's as ZigZag. This makes lots of vibrations on the part.   Tried to change the Minimum Wall Flow 0-20% without effect. Tried with 0 and 100 infill without effect.   In the image the desired result is on the left.
