Bug 488328

Summary:	When using my Wacom 16 and Pro Pen 2 within the Krita canvas it is miss aligned. Meaning, when I attempt to draw the cursor is several inches to the right. This is not an issue outside of the canvas or within other programs, only within the Krita canvas.

This is unlikely to be a bug in Krita, since Krita does not have any tablet-specific code: that's all OS, driver and the Qt framework. The reason you don't see misalignment outside the canvas is because to everything outside the canvas, the pen looks like a mouse. Reasons for misalignment on the canvas can be:

* buggy Wacom driver (I once had to buy a Cintiq and a Wacom Remote to figure out that for quite a few versions, having the remove first in the list of devices triggered an offset bug)
* On Windows, incompatibility with either the wintab or the windows ink driver: you can try switching between the two in Krita's tablet setttings page. Restart to make the switch active
* Faulty settings in the Wacom tablet driver app
* A broken settings file for the wacom tablet driver app

But, as I said, there's way for us to "fix" this in Krita's code, even if this bug doesn't appear in other applications: tablet drivers contain a lot of application-specific workarounds.

Thank you for your swift and helpful response. For my particular issue the solution was adjusting the Krita tablet settings as suggested. My Wacom driver seemed to be incompatible with the wintab settings.
