Why does the knife tool create random extra geometry? The knife tool seems to be generating duplicate vertices, creating additional unwanted geometry. Is this a bug or related to camera or tool settings?

Any idea?



edit:
Clarifying the vert:
try using line tool instead, it is pretty similar to knife tool, works pretty well and has some additional functionality, like create faces and objects
