Retopo bug

Hi. I found a bug in retopo mode. Whenever I'm trying to to extrude vertex it sometimes switches to polygon creation instead and while it registers, produces edges with zero lenght. It also occures with tweak tool.

Can you make a video to show off the bug? I don't know how to reproduce it.

Do you still have the problem?

I'm currently using older nvil version and haven't had time to investigate problem aby further yet. I'll try to check and if issue still persists, record the video for you.

Finally had some time to play with Nvil and sadly bug is still there, can confirm I encountered it on 2 different machines. Here's the video.

You can notice that at few points it tries to create poly line instead of grabbing vertices. I also found some other odd behaviour that was rather hard to replicate but I managed to capture single instance of it, at 0:16 mark you can see that vertices close to the cursor are getting slightly displaced on their own, don't know why it happens. What's worse its undoable, sometimes because of this it reprojects displaced vertices to distant mesh parts and I have to move back the vertices to their original position which is really annoying.

The screen is too small and I can't tell which tool you were using. Is it the Draw Mesh tool or the Teak tool?
Did you use the same mouse on the two machines?

Back to you first post, I am somehow confused.
When you said "extrude vertex" you meant moving it, right? Not extruding vertex like extruding polygon which creates new geometries.
And how can you tell it switched to polygon creation not something else?

It happens in retopo mode, using either tweak or drag extrude vertex, I think it's even happens when using drag operation on edges too. I would have to check if it also occurs outside of retopo mode. Sorry for the confusion.

Try this and see if the bugs still there.

I played with new version for a little bit longer and it seams that issue is gone. Thank you!
