Having this Brush jitters

System
Windows 11 pro x64
Ryzen R5 3500
RAM DDR4 16 GB
GPU GT 730 4 GB DDR3
Tablet : Huion K46

Now I am having this brush jitters in Krita which I usually don’t get in Photoshop or CSP.

I don’t have K46’s driver installed because last available driver on Windows 11 from Huion is for K58. Also using that driver though it support my tablet kind of kills its pressure sensitivity across all the apps. So I generally use the out of the gate Windows ink driver which is actually working great for me.

I tried using brush stabilizer, but the problem persists.

Most Windows users find they have to turn off Windows Ink in both Krita and their tablet.

Are you able to make a Krita profile within your tablet’s interface so you can use the K46 driver for Krita (so no Windows Ink) and not mess up your settings for other apps?

Problem is that if I install K46 (K58)'s driver the pressure sensitivity stops working for all other apps, Blender, Zbrush, Photoshop. That’s why I try to avoid using it.

Ooh, that is tough to figure out what else to try. There may be others here with some more ideas.

Hello @Ulfric and welcome back :slight_smile:

When did this start?
Is its starting associated with any event such as updating the version of krita or a Windows system update?

Is your image a screenshot?

Which brush preset are you using?

What is the canvas size?

If you use a canvas of double that size, does the jitter decrease?

You should be able to do that with the older driver.
Can you? If you can then it would be good to do that.

Did you fully and properly uninstall the previously tried driver at each stage with a full power down restart at every stage?

  1. Yes it is a screeshot
  2. I was using the normal Pencil
  3. I don’t use large canvas much, it was 1920x1080 with 72 ppi

It has been persistent for a while, With K58’s driver it doesn’t happen, but then as I said before the pressure sentivity stop working on other apps like Zbrush, Blender, Photoshop.

This is a fresh windows install on a new SSD. In this fresh install I haven’t installed the driver for the tablet because of past experience.

I am trying to commit to Krita while abandoning Photoshop, only this issue is stopping me from doing so.

We’re talking about the jagged look of the lines? To me that just looks like what you get if you’re zoomed pretty far in and draw with a one-pixel brush

Could you provide a screenshot of the whole Krita window?

That implies that there is some kind of generic Windows driver for tablets that is being used. Or, Windows has recognised that you have a Huion tablet and has installed what it thinks is a suitable driver.

What tablet settings/config do you have, if any?
From the Windows start menu, do you have anything if you search for ‘huion’ or ‘tablet’ or similar relevant words?

It’s the driver that comes bundled with the Windows. Unlike the GPU windows don’t really install the driver for the tablet. If there is none it just uses the default inbuilt driver.

Sure give me a moment


Krita 3840x2160 still jittering


CSP 3.0
2000X2000 no jitters

It’s also what you get if you draw with a 5px pencil and zoom out:

I have posted a new screenshot from Krita & CSP as well.

Great! How does it look at 100% zoom? O’m wondering if this is just display filtering or something to do with how the actual stroke gets drawn.

Also, in Settings → Configure Krita → Tablet settings, do you have Wintab or Windows Ink enabled?

If it’s Wintab then the obvious thing do do is enable Windows Ink then press Ok and restart krita.

If it’s Windows Ink then as an experiment, enable Wintab then press OK and restart krita to see if that helps.


normal


100% zoom

Ok, that’s definitely in the stroke itself. My hunch was incorrect.

Worked. I had Win+Tab enabled. Changing it to Windows Ink solved the issue

Aha! Enough stabs in the dark in different directions will eventually kill the monster :slight_smile:
(There may be collateral damage.)

Thanks mate, also thanks to @hulmanen @sooz as well.
