Crash on Windows 10 when node handle is moved

[Debi Dalio]

Inkscape 0.92.1 rev 15371
Windows 10 on a Microsoft Surface laptop with a Dell monitor at 3840x2160.

Draw a line containing multiple nodes with the Bezier curves tool.
Accidentally grab a node handle or the line instead of the node handle you're aiming for.
Move the handle or line in the direction in which you were planning to move the node.
The node handle flies around and causes an instant crash.
See attached screenshot.

This problem happens frequently for me because nodes are so tiny that they're hard to grab.

I'm not able to reproduce this crash on Windows 10 with Inkscape 0.92.1 r15371 (64-bit)

Could you maybe upload a file that you can make crash easily (with detailed steps on how to trigger the crash)? You're likely hitting some border case here that happens easily in your scenario, but might be almost impossible to reproduce in others.

I just tried to reproduce the error and now it's not happening. I don't know what might have been special about those two days on which I had the crashes previously, but I haven't had the problem since then. If this crash happens to me again, I will immediately make a copy of the file and if I can reproduce the error with that file then I'll send it to you.

Well, the crash happened again, but I was unable to reproduce it voluntarily.

Frankly, I find Inkscape 0.92 on Windows 10 64-bit to be unusable due to several problems that keep cropping up. Besides the random crashing, I also frequently have problems with parts of a design disappearing while I'm working on it and I have to zoom in or out to make it be redrawn. Sometimes I'll be moving around the screen editing nodes on a line and part of the line disappears. I've also several times had a problem with copying a set of objects from one svg file to another and finding that some of the group objects were missing some of their parts or showed up with the wrong color. These problems are so annoying that I have uninstalled 0.92 and reinstalled 0.91 win32.

I have the same (or very similar) problem on Ubuntu 16.04:
