When using my tablet with the beta builds the painting happens at the left-top part of screen only. It seems the pen position is mapped to only the left-top corner of the screen. When working at 1920x1080 it is 1/2 the width and 1/2 the height, when working with 4x resolution it seems to be about 1/4 the width and height. Works: 2.9, krita3-prealpha3-de0d43d Does not work: krita-3.0-Beta-master-962bfe1-x64 krita-3.0-Beta-master-4a58260-x64 krita-master-f38b47e-x64 Reproducible: Always Steps to Reproduce: 1. Open Krita 2. New image 3. Paint using pen Painting with mouse works Controlling GUI widgets and color picker with pen works Right-click circular menu appears at the wrong position as well when using pen

After some more investigation, it seems it is using the top left approximately 700x480 pixels. Could be related to tablet resolution? I am using a Wacom Bamboo Fun Pen & Touch Medium
Hi Jonathan, Which tablet do you use? And do you have display scaling enabled in Windows?
The really interesting thing is that only the version that uses Qt's hidpi awareness seems to map correctly for you. That's extra-double-plus strange, because setting the display scaling in Windows doesn't make any difference for me on my SP3...
I am using display scaling of 125% A more precise measurement suggests that only the topleft 640x480 area is used.
Weird... I just put my SP3 at 125% scaling, and everything worked fine (but that's with the built-in ntrig pen + wintab driver, so it's not exactly comparable...) Can you try to generate a tablet log as per https://docs.krita.org/KritaFAQ#Tablets ?
I suspect that this commit causes the issue: commit 23596b92c5f1ad05379ac4e7f65a1350a6e5f2ba Author: Michael Abrahams <miabraha@gmail.com> Date: Tue Mar 15 09:40:48 2016 -0400 Support DPI switching in Wintab coordinate scaling Read current DPI from qApp->activeWindow->devicePixelRatio()

For me it works fine now, not only in the newest build but also in the builds mentioned in this bug. Maybe it was fixed by a windows update???
That is not entirely inconceivable, since the converse happens all the time as well :-)
