Snap to Point causes jumping with long Guides
I'm using very long guides to create a custom angled grid, and use Snap to Point to snap paths to intersections of those guides. However, sometimes the Snap to Point causes "jumping", i.e. it tries to snap to the intersection, but when it does, it scrolls the document a tad upwards, and hence goes immediately out of snap. Sometimes it even causes jumps of hundreds of millimeters. It doesn't always happens, but only with some guides intersecting in some points. I cannot really say what actually makes it happen.
I created a test file to where I isolated only three objects, the path with three vertices and two long guides intersecting. when trying to move the middle vertex to the guide intersection, it always jumps. It also happens if I paste them to a new document. It also happens even if I move the guides anywhere on the document.
It only happens with guides, not when I release them back to paths. But, if I release and re-make guides, the problem still persists.
However, strangely enough, if I take the diagonal guide and cut & paste (Paste in Place) it back to the same document, the problem goes away. This happens if I make the cut & repaste with either guides or guides released to paths and remade to guides.
The guides were originally created en masse with just two lines and duplicated with Blend (thousands of lines), and then duplicated in different angles. I'm not sure if that affects this problem.
(I'd just use paths to help alignment, but with thousands of lines the guides seem to burden the rendering much less.)
any comments on this, Illustrator CC is terrible for unwanted snapping to grid / point. How on earth do you stop this infuriating behaviour (menus say it's off but it keeps occurring)??
