I'm constantly on the search for solutions to this problem. Every rabbit hole I find, I dive in. Including this one. Here is it, 2019, and I'm still having this problem. The white workaround doesn't work around anything for me. I'm on PC, Windows 10. The polygonal lasso tool continually snaps closed before I've finished the selection, and I can only use it with the mouse. Neither of my wacom tablets can use the tool at all because it sticks and becomes unresponsive. It is the most frustrating issue I've encountered over the last several updates.

Updates to drivers, os, graphics card, new pen, new battery pack, command prompts, clean unstall/reinstall, ad nauseum. This problem happens with my laptop and my desktop, two different tablets (one old, one new). I despair of a solution.
