**Blender Version**
Broken: version: 2.91.0 Alpha, branch: master, commit date: 2020-10-06 20:17, hash: `rB099ce95ef36d`
Worked: I have that problem since 2.80 i believe - dunno if it worked properly before 2.8
**Short description of error**
Sometimes the clay strips (and other brushes like the clay thumb) brush messes up the mesh like in the video. The normal draw brush works as intended.
It seems like it only happens on thinner parts of the mesh/object.
**Exact steps for others to reproduce the error**
Use the attached blend file, choose the clay strips brush in sculpt mode and use it on the mesh.
