Bug ID: 361565
Summary: Brush and cursor do not line up when second monitor is
used.
Product: krita
Version: 3.0 Alpha
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: OpenGL Canvas
Assignee: krita-bugs-***@kde.org
Reporter: ***@outlook.com

I am running Krita 3 Alpha 3 git de03d43d.
Surface book -Windows 10

This bug only manifests after adding a second monitor via HDMI. When using
without a second monitor or if the second monitor duplicates the surface book's
tablet screen, it seems to work fine.

The bug: When using the surface pen, the brush and all other tools are offset
from the cursor on the X axis. The offset increase as the cursor is moved to
the right of the screen and decreases when moved to the left of the screen. If
the surf-pen is moved to 0 pixels on the X axis, the left edge of the tablet,
the cursor and brush are together.

When using a mouse, the cursor and brush are synchronized and work normally.

Reproducible: Always

Steps to Reproduce:
1. Open a new canvas in Krita 3 pre-alpha 3
2. Connect Surfacebook to another monitor via HDMI
3. Pick any tool and apply to canvas to see the offset.

Actual Results:
Tools work normally, except they are all offset from the cursor on the X axis
by approximately cursorX * 1.5.

Expected Results:
When an additional monitor is added, Krita tools should continue to be
synchronized to the surf-pen's cursor position.

Screen Resolution: 3000 X 2000 for surfacebook tablet screen
Screen Resolution: 1920 X 1080 for secondary monitor screen

Love Krita so far, y'all are doing a great job. Please keep me updated on the

Oh, and does this also happen with the real alpha? If not, it's another Qt
hidpi bug, probably.

This fixed the cursor alignment issue for me (Cintiq 21UX 2) but after setting
the resolution manually Krita no longer recognizes pressure sensitivity.

This fixed the cursor alignment issue for me (Cintiq 21UX 2) but after
setting the resolution manually Krita no longer recognizes pressure
sensitivity.
Additional details:
Holding shift and touching a newly opened Krita canvas with the stylus brings
up the Screen Resolution dialog in Krita 2.9.11 as described in the link
provided by wolthera.

After setting the correct resolution in 2.9.11 the brush cursor was correctly
aligned with the stylus tip again but I was unable to to get pressure
sensitivity working. I navigated to AppData/Roaming and renamed the Krita
folder to Krita_bak which restored the pressure sensitivity but also
reintroduced the brush/cursor offset.

Next, I downloaded Krita 3.0 RC.1 and found that wolthera's method no longer
works at all on this release. I did find that if I open a Windows Explorer
window over the Krita window the brush cursor offset disappears when hovering
over Krita's canvas. When I actually press the stylus tip to Krita's canvas,
however, the stroke although not offset is drawn with 100% pressure. When I
lift the stylus the offset returns on the next stoke and pressure sensitivity
is back to normal.

Sadly this blocks me from using Krita in production.

This is on Windows 7 x64.

The resolution conflict dialog is back, so I can resolve this bug.
