Description

Issue I believe with indexing of snapping.

If you add in a WFS layer non-cached, so that it only loads in the extents of your screen. Turn snapping on for that layer. Create a new feature in a different layer (at which point the WFS layer is indexed in order to be snapped to quickly). Then pan the map to bring in new features from the WFS, you can not snap to the new features. The features in your initial view extent can be snapped to, but the new ones cannot be. Turning editing off and on does not resolve the issue.

I have attached an image which may clarify the issue.

I have tested this on 2 different WFS servers.

It can be tested on the Vienna city WFS from:
http://data.wien.gv.at/daten/geo?version=1.1.0&service=WFS&request=GetCapabilities

Tested in QGIS 2.8.6 and 2.13 (2bacece) in Windows. Cannot test in 2.12 as the WFS does not fully support non-cached WFS.

Tested in 2.14 as well. Still and issue. It would be good if indexing for snapping could be turned on/off either completely or on a layer by layer basis.

I am experiencing the same issue in 2.14. Snapping stops working. Auto-trace does toggle snapping but temporarily.
