Broken: 3.4
Worked: 3.3Lts

Caused by b5f7af31d6

Short Description
If you use the smooth brush while face sets are hidden. The geometry acquires significant artifacts.
The same operation did not cause these artifacts in 3.3

To reproduce

Open the attached blend file. It is a sphere with some hidden face sets.
In sculpt mode, use the smooth brush on the large white face set.
You should observe artifacts.

Guess this should be treated as a separate report?

Unhide all the face sets and the smoothing brush should then behave normally.
Hide all the face sets except for one of the small ones.
Try to smooth that face set and smoothing will have no effect at all.
