Not replicable here on Ubuntu 64bit. Does it happen with all point layers? just with point layers?

it happens, when you use the nodetool to move the point.

The original issue disappeared, thanks !
However it seems the snapping of points doesn't work anymore because of this patch. For example, if I want to use snapping on a segment and move a point using node tool, the point will not snap to the line, but go a certain distance away. If I follow the line while continuously holding the mouse button, the point will follow and remain at the same distance.
