Hi,
I'm encountering an issue with sculpt tools in v4.3.4
I put a cube through primitives, I use draw sculpt tool to add some bumps.
Then when switching to smooth tool, smooth tool doesn't apply at all on some parts of object.
When I switch the Lines On using Lines On/Off button, then smooth tool correctly works applying to any part of object I click on.

Is it an known issue sculpt tools doesn't work properly in Lines off view?
