Wintab : stroke jitter at low zoom levels when drawing slowly

I'm using Photoshop with a Wacom pen display (Cintiq Pro).

When Photoshop is configured to use Wintab, pen strokes may show noticeable jitter at low canvas zoom levels (for example, 12.5%), especially when drawing slowly.


Symptoms:

  • Most visible when drawing smooth diagonal or curved lines
  • Appears similar to low-resolution screen coordinate input
  • Stroke position accuracy is reduced
  • More noticeable at lower zoom levels

The pen tablet seems to be behaving as if its tracking accuracy has dropped to the level of the screen resolution. In terms of actual hardware performance, the accuracy should be the same as Windows Ink.


System:

Wacom Cintiq Pro, and dual-monitor setup (total 3 monitors)
wintab enabled
Photoshop :from older to recent version all

This is additional information.

The creator of lazynezumi points out that this is due to a design flaw in Photoshop's WinTab feature.
Furthermore, the details of the issue seem to match this behavior.

Setting aside whether the specific details are correct or not, in fact, thanks to this software's “jitter bug fix” option, I've been able to maintain the expected line-drawing performance.
As noted elsewhere, this has remained unchanged for over a decade.

I know you're probably going to tell me to use Windows Ink, but because of the Slider's snapping behavior (which I mentioned in another post), It causes me  frustration.

IME Windows Ink has been the better choice API for a good few years now.  It’s usually plain sailing with Wacom tablets. Compared to the Chinese tablets.  Guillaume has been incredibly helpful on the few occasions I asked him for help, and his guide to tablet issues is the best resource I know of for pen tablet issues.

I don’t where you are at right now, but I would rename the Wintab text file (change the extension to OLD) and turn Windows Ink on in Wacom preferences.  If you have already tried that without success, get back to us.

Thank you for your reply.

As you pointed out, this line jitter does not occur in Windows Ink. I once used Windows Ink, and I switched back to it to verify this for this post, and I was indeed able to draw smoothly.

 

The link below, I discribed the snapping behavior of sliders in the photoshop UI when using Windows Ink.
This behavior is the reason why I can’t fully transition to Windows Ink, and it’s something I’m currently struggling with.

Hi ​@Rocketbottle,

 

Thanks for reporting this and for including the detailed steps and environment information. Could you first update to Photoshop 27.8, which was released today, and check whether the issue still occurs?

 

• Open the Creative Cloud Desktop app
• Click Check for Updates
• Install Photoshop 27.8 if it is available

If you don’t see 27.8 yet, please give it a day or two, as the rollout can take a little time depending on the region, and then test again.

 

Also, I wasn’t able to access the video from the link you shared. Could you please upload the recording to Google Drive, Dropbox, or a similar file-sharing service and share the download link here?

 

If the issue persists in 27.8, we’ll want to send the video and reproduction details to the product team for investigation, so having an accessible recording will be very helpful.

 

Best,
Anshul Saini

Thanks for replying

I installed the latest updates. Unfortunately, the problem still exists.
Here is a new link to Google Drive:

(PS. I am able to open the previous video link, and my Adobe library shows in Russian! What!?)

Photoshop 27.7.0 release

macOS 15.7.7

 

Wacom Intuos Pro PTH-660

Wacom Driver Version 6.4.13-4

 

Smudge Tool has a problem when using the Wacom pen and a soft brush with dynamics.

  • select the Smudge tool
  • Select a default brush with softness and shape dynamics settings (size, transfer, etc.).
  • Hold the cursor still or move it very slowly; the Smudge brush position jitters constantly by a few pixels, making precise control impossible.

Hard 0 % softness brush and a brush without any size or transfer dynamics, or using a mouse, works as expected.

 

I have attached a video clip of the problem. Please see the link below:
