Short description of error
wrong stroke displacement with strength pressure enabled
Exact steps for others to reproduce the error
in the 2d animation work space, using a drawing tablet with the regulation of the strength linked with the pressure of the pen gives an unexpected behaviour. The newer line is covered by the older path, unlikely with a real draw. Tested with Wacom Intuos S tablet and also with xp-pen artist 12, the issue seems to be blender-related, as the same doesn't happen with other drawing applications. Also tried in the daily build blender 2.8.1 beta. i shared a gif for illustration and also a sample project with a couple strokes.
