System Information
Operating system: Windows-10-10.0.19043-SP0
Graphics card: Quadro RTX 5000/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 472.39

Blender Version
Broken: 3.1 and newer
Worked: 2.92.0

first regression came with 6e77afe6ec
(occluded faces being selected)

second regression came with 690ecaae20
(not the whole enclosed are being selected)

Short description of error
Knife Project in 3.1 version is selecting more faces, even faces behind the view (cut through is off).

Exact steps for others to reproduce the error

The problem (in version 3.1) occures when the cutting lines extend over the border of the object. When the cutting lines are not extending over the border the tool (Knife Project) works as in previous versions. Attached files show differences between Blender versions. Images 1-2 show version 2.92.0, 3-4 show version 3.1.

In my case, it is actually selecting less faces (but also wrong)

This actually regressed in two steps:

first regression came with 6e77afe6ec
(occluded faces being selected)

second regression came with 690ecaae20
(not the whole enclosed are being selected)

Philipp Oeser changed title from ~~Knife project - Different results between versions (3.1 and 2.9.2)~~ to Regression: Knife project - selection after operation is wrong
