Comment 1 for bug 1693615

I've reproduced it. I haven't had a crash which produces the same error message, but I've achieved a fatal freeze.

Initially I thought the problem was related to being at a high zoom. But I've been able to reproduce it as low as 1600% zoom (and as high as the maximum zoom (25600%)).

Placing the Node tool mouse pointer in approx the blue circle in the attached zc1.png, the pointer changes to the "finger" (erroneously in my view). When I click-drag to select all 3 nodes, I see the same ghosting which is reported by the OP (see zc3.png). And the path shoots off the page.

I don't know why the finger is showing up when the mouse is clearly not over the path. But what seems to be happening, is that Inkscape thinks the mouse is over the path. And when I drag to make the selection, it's actually editing the path.

I also don't know why such a small movement of the mouse results in such a huge change of the path. See what it looks like at 100% zoom, in zc2.png. A movement of the mouse less than a pixel (while zoomed) creates (in my tests) a "curve" in the path as long as 500 pixels. (500 out and 500 back)

At first I was thinking that the path must be shooting so far for the OP, that it was making the file so huge that it crashed. But since I've achieved a fatal freeze (with 16 gb RAM), I think something else must be happening to cause the freeze or crash, something besides, the erroneous "finger" and exaggerated path edit. (Maybe what I've heard referred to as a "memory leak"?) But of course I'll have to leave that to the experts to determine the cause.

Maybe there is more than 1 problem happening here? I'm not sure. For the record,

Window 7 Pro, 64-bit, 16 gb RAM, Inkscape 0.92.1, 64-bit, exe installer

Any additional info needed, just ask :-)
Thank you very much!
