# Physics: Why does the cube with a hole and fit cylinder not work together?

I tested this simple setup where i created a 4x4m cube and created a 1m radius hole using boolean operation with a cylinder. So now i have tightly fit in the exact cylinder i used to make the hole and I've also reduced the radius of the cylinder by 0.05m with ALT+S to create this decent-sized gap as shown in the image below. Unfortunately it seems that this is not enough because the physics doesn't work. It keeps vibrating as if they are constantly in a state of violating the physics law of impenetrability. It does work if i decrease the cylinder by another 0.05m but that is way too big of a gap. I need the 2 objects to be as tight together as possible. How do i do that? I'm using collision shape mesh and tried all sources (final, base, deform) but unfortunately nothing works. I also checked the face normals orientation and it is correct; all faces are blue.
