System Information
Operating system: Windows-10-10.0.17134 64 Bits
Graphics card: GeForce GTX 970/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 388.13

Blender Version
Broken: version: 2.80 (sub 74), branch: blender2.7, commit date: 2019-06-07 23:24, hash: 749d53effd
Worked: (optional)

Short description of error
When using the Knife Tool, it often creates artifacts of geometry, especially with complex cuts.

Exact steps for others to reproduce the errorknife_tool.blend

1 - create a cube
2 - create a cut from the corner into the middle of the adjacent face. Then click outside the geometry to create a section through this and the adjacent polygon.
3 - repeat several times

(the more complicated the geometry, the more bizarre the mistakes created by the Knife tool)

This isn't enough information.

Checking here and it's working as I would expect it to.

Steps are needed to reach the point where the first error is made, with an image or blend file showing the error state.
