Godot version:
current master of 3.1
OS/device including version:
Win10 960m
Issue description:
The new slider boxes in 3.1 don't work at all with a Wacom tablet. I am using an Intuos Pro, but this problem likely exists with all models. The sliders with the circle work ok, but the slider boxes with no graphical slider just jump to a random location in the positive direction, regardless of how much I move the cursor or in which direction.
As illustrated in this gif, I am only very slightly moving the cursor for these massive jumps. I should note that every other piece of software I use works with a Wacom correctly, including non graphic apps like DAWS and browsers.

Steps to reproduce:
