System Information
Operating system: Linux-5.4.0-72-generic-x86_64-with-glibc2.31 64 Bits
Graphics card: Mesa DRI Intel(R) HD Graphics 4600 (HSW GT2) Intel Open Source Technology Center 4.5 (Core Profile) Mesa 20.2.6

Blender Version
Broken: version: 2.93.0 Beta, branch: master, commit date: 2021-04-24 18:46, hash: f7afd78b80
Worked: in Blender 2.92

Short description of error
Strange artifacts using 3D sectioning using Boolean modifier - Intersect (see sectioning animation issues below)

Expected behavior:
3D slice working correctly in Blender 2.92 (to view internal section of object)

-Create Mesh Plane (larger than object)
-Select Plane - Add Boolean Modifier 
	Options - Intersect
	Object  - STL or Object
	Solver  - Exact

Actual behavior:
3D slice issues using Blender 2.93 beta (to view internal section of object)

Not showing object as a 3D section like in 2.92 (see animation above)
Artifacts Showing up when moving cutting plane back and forth (see animation below)

Exact steps for others to reproduce the error

In the blend file, move the Plane_xy along the z axis, or move the Plane_xz along the y axis.
