Digitising & snaps

Added by Jakub Kosik over 8 years ago. Updated about 8 years ago.

Pull Request or Patch supplied:No Resolution:worksforme
Crashes QGIS or corrupts data:No Copied to github as #:19305


I've started work on big project with digitising in QGIS, and found some bugs when snapping:
1. When I try to move poligon or few polygons (red-line - dig1.png), snapping to same layer - sometimes cretes new vertex instead move (dig2.png);
2. When I move vertex and snap to semi-transparent or black-line polygon layer I got effct: dig3.png - new vertex is crated on far, far away random polygon from edited layer and snapped together.

Problem is rather old, I've noticed that in 2.2, 2.4 and 2.5

a few screenshot do not help understand well how to replicate this issue. What would be needed is a sample project and data (with the snapping options already defined as necessary) and/or a screencast (to help understand at what scale are you working, what steps to make, etc.).

I cannot share this data due to law restrictions. I'll try to create some screencast. Now I'm collecting data outdoors with QGIS and Windows-tablet
