Seems to work for me. @mano-wii, am I doing something wrong?

@giakaama, do you have the same issue still?

It's still broken for me:

Avoid orbiting the 3d view.

Weird, I'm trying to copy you as closely as possible, but still cannot reproduce it.

{F8542769}I can confirm this, and this happens if you use a Tool from a shelf or pres K button. If the tool is activated with the command from the search box it seems to work correctly. Don't know what is a difference in thous 2 but there is.
First, when you activate a tool with K it doesn't show green vertex snapping dot. but when you do it with a command like in your Video(Jacques Lucke) it does show dot straight away.

UPDATE: after a bit more use of knife tool from search box it started again do the same thing as Germano shows, making weird cuts.
