Bug ID: 384843
Summary: Brush freezes after lifting stylus pen away from
tablet while cursor is on canvas
Product: krita
Version: 3.2.1
Platform: MS Windows
OS: MS Windows
Status: UNCONFIRMED
Severity: major
Priority: NOR
Component: tablet support
Assignee: krita-bugs-***@kde.org
Reporter: ***@gmail.com
CC: ***@gmail.com
Target Milestone: ---

I'm experiencing exactly the same bug as [333843], but on Windows 8.1 with
Wacom Cintiq tablet. So, I just copied the description from [333843]:

If I lift the pen away from the screen (beyond hovering range) while the cursor
is on the canvas, when I put it back down on the canvas, the brush stays frozen
where it is and does not move until I move the pen over another part of the
screen (other than the canvas).
If I lift the pen away while the cursor is anywhere other than the canvas, it
works normally when I put it back down.

Reproducible: Always

Steps to Reproduce:
1.Hover pen over tablet so that cursor is anywhere on the canvas.
2.Lift pen away completely.
3.Put pen down straight back onto canvas and try to paint. The brush stays
where it was.
Actual Results:
The brush stays where it was when the pen was lifted away and will not move.

Expected Results:
It should jump to wherever the pen comes back down and keep following it.

Tablet: Wacom Cintiq 13HD touch (last driver version: 6.3.24-5)

Have you got mouse mode enabled for your tablet?

I'm not 100% sure, but I think this is irrelevant for Wacom Cintiq. This tablet
has its own display and works only in one mode, which is a pen mode, I guess...

After you asked I tried to find corresponding switch in Wacom Settings and
didn't find anything similar...

Well... It must be some kind of configuration issue, because I cannot reproduce
with either my cintiq or my mobile studio pro :-(. Though that's with Windows
10, I haven't got a working Windows 8 system anymore. I wonder if I would load
a back of your wacom settings, whether I could reproduce it.

Do you want me to save my wacom settings and send it to you? OK. I'm
sending via email, because bugs.kde.org has file size limit.

Yes, sure. Done.

Huh, there's something really wrong with your Wacom configuration. Krita isn't
getting any tablet events other than TabletEnterProximity and
TabletLeaveProximity, which means you are not even getting any pressure
sensitivity.

Try resetting your Wacom driver config, uninstall the driver fully, and
reinstall the driver after that.

Done. The problem is still there.

Sorry, but I disagree. For me it looks like a Krita issue, because other 3
graphics editors work with my tablet: Manga Studio (Clip Studio Paint), GIMP
and Photoshop. And all of them are responding to the pressure of the pen.

I'm sorry, are you using a Wacom Cintiq 13HD touch? Do you have external
monitors? Because from the tablet log, both the WinTab driver and Qt reported a
screen resolution of 5760x2160, but the resolution of a Cintiq 13HD should be
only 1920x1080. So this points to a Wacom driver config issue.

This issue looks to be similar to bug 384504, and that was a Wacom driver
config issue. I'm not sure how the reporter solved it, but it likely involves
resetting the Wacom driver settings with the driver utility and messing with
the calibration.

This really just makes the issue more confusing. It could be that those
applications are using Windows Ink instead of WinTab, but there shouldn't be
any reasons why it works in Windows Ink but not WinTab, unless the Wacom driver
screwed up (again).

Could you try this experimental version of Krita with Windows Ink support
(enable it in settings/configure krita/tablet):

https://files.kde.org/krita/3/windows/devbuilds/krita-3.3.0-pre-alpha1-x64.zip

And see if you do get events from the windows tablet system, instead of the
wintab system?

Yes, I use Wacom Cintiq 13HD touch.

Yes.

5760x2160 - is a sum resolution of all monitors: One, main (3840x2160) - on the
left side, and two on the right side: TV (1920x1080) and Cintiq (1920x1080).
Cintiq is below the TV in the virtual space. That is why resolution = 5760x2160

I've just tried this solution:
https://www.reddit.com/r/krita/comments/5s1tuu/how_to_fix_multi_monitor_pen_pressure_issue_in/?st=j7rlma4w&sh=6fb45b01

...and it worked!!!

Maybe it was a driver or configuration issue, because I already saw this
resolution-conflict-dialog before, and already selected this first option with
"WinTab" before...

So, it looks like the problem is already resolved.

But if you want me to check experimental version - ask me, I will be glad to
help.
