Comment 2 for bug 1814411

This sounds like you sometimes miss the dragging phase when creating a node by clicking. You need to make sure you drag out actual bezier handles after each click. If this isn't the explanation please open an issue on the new bug tracker https://gitlab.com/inkscape/inbox/issues

Closing because I can't reproduce this in 1.0alpha (1:0.92.0+devel+201904052254+98d368e) on Ubuntu 18.10.
