I want to switch from Photoshop to Krita but I encounter an issue.

In the Wacom Tablet Properties, Mapping tab, there are 2 choices for the modes : Pen and Mouse.
I usually use draw with the Mouse Mode and the behavior of my pen is not what I should expect from it...The pen cursor jump here and there without control...

Am I the only one ? Is there any solution ? Someone can help me ?
