I've been editing the vertices of some polygon layers to snap them to a point layer. I turned on snapping, select the vertex of the polygon I want to move, click and move it towards the point and my cursor does "snap" to the point feature. The vertex does move close to the point feature, but if I zoom in closer I can see that the vertex and the point are not actually coincident. It seems I have to zoom in to a 1:1 scale to get the vertex snapped appropriately. Has anyone else experienced this issue?
