            Bug ID: 373191
           Summary: Drawing has either "no pressure sensitivity+freezing
                    brushes" or the brush is offset from the pen depending
                    on the info in the "Choose Screen Resolution dialog"
                    on multiscreen (cintiq)
           Product: krita
           Version: 3.1 Beta
          Platform: MS Windows
                OS: MS Windows
            Status: UNCONFIRMED
          Severity: grave
          Priority: NOR
         Component: OpenGL Canvas
          Assignee: krita-bugs-n...@kde.org
          Reporter: kirtai2...@yahoo.com
  Target Milestone: ---

I have a three monitor setup as follows:
1920x1200 (monitor) 1920x1080 (monitor) 2560x1440 (Cintiq 27QHD)

In the "Choose Screen Resolution" dialog, the wintab and Qt autodetected sizes
are 6400x1440, offset 0x0

If I accept this, the brush draws on an offset from the pen position.

If I change it to manual and input a size of 2560x1440, offset 0x0, the brush
now tracks the pen perfectly. *However*, pressure sensitivity stops working and
the brush freezes in place when I lift the pen while it's drawing.

I've seen these two bugs reported before but this seems to be a common cause
and I can trigger either at will just by changing the screen resolution
settings.

I have experimented with different screen resolution settings but they all
produce either offset drawing or no pressure sensitivity with freezing.

This only happens in kritas canvas. MyPaint, Clip Studio Paint, Drawpile and
others all work correctly.

I have marked this grave since it seems impossible to have both an accurate
brush with pressure sensitivity which doesn't freeze on lifting the pen.
