When I try to draw using my wacom I get this weird bug where it draws a line and then acts as though the brush is a couple inches away from where the cursor is.
The weird thing is that when I draw with my mouse it works fine, so I think it's just the wacom.
Here's a gif of what it looks like when trying to use the wacom. Link to gif
The first thing I would do is uninstall all wacom drivers and download/install the one specific for the tablet you currently have connected.
