System Information
Operating system: Windows-10-10.0.19041-SP0 64 Bits
Graphics card: AMD Radeon RX 5700 XT ATI Technologies Inc. 4.5.14757 Core Profile Context 20.11.2 27.20.14501.18003

Blender Version
Broken: version: 2.92.0, branch: master, commit date: 2021-02-24 16:25, hash: 02948a2cab
Worked: (newest version of Blender that worked as expected)

Short description of error
Face > Intersect (Boolean) does not work properly with an unapplied Mirror Modifier, it removes the mesh along the existing edges instead of creating new edges.

Exact steps for others to reproduce the error
Highlight cutouts (cylinders) and goto Face -> Intersect (Boolean) I tried the same thing with simple cubes and it worked as expected.

I can reproduce this in 2.92 but not in the latest 2.93 Alpha. Seems like the issue has been fixed already. @ViperMageEX Could you try the latest Alpha from https://builder.blender.org/download/ to make sure?

I can't see any commits in #85958 that would indicate the fix. @HooglyBoogly any idea what commit might have fixed this?

Yes, my guess is 6f63417b50 which made boolean work better on non-manifold meshes. So as far as this commit is concerned this is technically more of a feature request. I'm happy it works in 2.93 at least.

Alright, do you think it would be ok to add it to the list of fixes for #85958?

I don't think I'd do that, a requirement of manifold inputs is not to unreasonable to have for the rest of 2.92 I don't think. That's just me though.
