Cube Mapping with stencil results in inconsistent mapping results between brush modes

Hello!

I have been using stencils to get sculpted detail on meshes, it works great!

However there is some weirdness I have noticed between different brush modes:

An overview: Cube Mapping with a box or lasso selection works great. But when using smooth shading on a matcap, for some reason the resulting normals look clipped and do not represent the geometry. Stamp works but only picks one projection angle, and stroke works but only with smaller brush sizes or you get the same streaking effect as stamp.

Step by step:

It appears the clipping issue is specific to smooth shading. This can be fixed by switching to flat shading, but I was misdiagnosing the issue because I was assuming wrongly that the heightmap alpha value range was getting clamped (I'm using 32 bit exr). normals update when you use another brush

I wonder if there is a way to get all bushes to use the stencil the same way the lasso tool does to avoid those long streaks?
