Short description of error

Huion Kamvas 22 pen jitter (?) and sometimes can select three values when changing one value on the user interface.

Original description

Dear Blender 3D Software Developers,

I hope this message finds you well. I am writing to report some peculiar issues I have encountered while using Blender version 3.6. I have been experiencing occasional strange behavior with my Huion Kamvas 22 Pro drawing monitor's pen, and I have not been able to identify the root cause of these problems.

Specifically, the pen seems to struggle to change values smoothly when I attempt to drag and scroll through them. Sometimes, when trying to adjust values, the pen's response becomes erratic, and it selects three or more values simultaneously. These issues do not consistently occur, and I cannot pinpoint what might be causing them. I would like to highlight that I did not encounter any such problems in the previous version (3.51) of Blender.

I have ensured that all my drivers are up to date, including the ones for the Huion tablet, and I have installed the latest Windows updates as well. While I cannot definitively assert that Blender is the cause of these anomalies, I thought it necessary to submit this issue in case others have experienced similar behavior or if the developers might have some insights into what could be causing it.

I truly appreciate all the hard work put into developing Blender and the wonderful tools it provides to the creative community. Please keep up the excellent work, and I wish you all the best in your future endeavors.

Thank you for your attention and consideration.

Best regards,

Imre Meszaros

Hi @Imre , By "Changing 3 values", you mean like three values on a XYZ array? If you drag the slider vertically initially you will be able to select multiple fields, so it could be your tablet jitters and caused the issue. I'm leaning towards hardware issue, and also I'd like to suggest not using such long paragraph that contains no information. Please refer to bug report guideline for how to be as effective as possible. Thank you!

Hi YimingWu, I mean three or more different values, which are not supposed to be changed together. For example on the Principled shader. Sometimes it selects all the values. Really strange. (I use Blender professionally every day since version 2.8, I'm aware that you can select X, Y, Z for simultaneous drag. )

YimingWu commented

2023-07-20 15:39:50 +02:00

@Imre Then the only way to explain the mechanism is that blender somehow thought the pen have moved vertically for a long (or some) distance, and jumps back immediately, that can explain why multiple values are selected. Have you had any jitter/weird movement issue in other programs especially drawing programs? Like it can produce spikes and stuff?

Well, that is only one part of the problem. As I said sometimes dragging values doesn't work either. Or I try to select an X, Y, Z Vector on the mapping node and I can only select one. It seems to me that something is changed in Blender 3.6 with the pen sensitivity or pen properties. When starting Blender, the issue doesn't occur immediately, as if some script or action is causing it. And when it appears, I have to restart Blender, and everything works fine again for a while. Could this be an add-on that is not compatible with the current Blender version? And no, I didn't experience any problem with the pen in other programs. I will test my pen display and pen for a couple of days in Blender 3.51, so we can be sure it is only a Blender 3.6 Problem.

Issues persist in 3.6.1?
I can test with Huion Kamvas 22 plus and not found same issues
I usually use Windows Ink as Tablet API in Input Preferences from blender, and Enable Windows Ink in the Digital Pen preferences in Huion app

I had the same setup only instead of Windows Ink as Tablet API I had Automatic. I thought that selects automatic the best API available. Btw yesterday I worked all day long with the 3.5.1 version, without any issues. Today I will test the 3.6 and Windows Ink as tablet API let's see if that makes any difference. As I said the issue seems to be random, I didn't figure out yet what causing it, so I can not reproduce it. I suspect this could be an add-on, which is not compatible with the 3.6 version.
@guishe Guillermo no, I haven't tried it with 3.6.1 yet, but if the issues persist that will be my next step.

@Imre with Windows Ink selected as Tablet API, issues did not show up again?

Indeed, it seems enabling Windows Ink solved the problem, although at the same time, I also disabled all the plugins I am not currently using, so it is possible that one of the plugins was causing the trouble. I'll let you know if anything changes.

@Imre , any updates? Did you identify the culprit? Was it a plugin or tablet API preference?

Imre commented

2023-09-01 16:03:10 +02:00

No I didn't identify the problem, but I also don't have this problem with the latest stabile version anymore. I also updated my plugins in the meantime.

Thanks for your time guys.

I guess we can close this issue then :). If the same problem pops up again please feel free to report again. Thanks!

Hello, @Imre I have same issue of "Specifically, the pen seems to struggle to change values smoothly when I attempt to drag ..."
I'm using Kamvas 22plus too and blender 3.6
I also own an old huion tablet(no display), interesting thing is. when I plug the old tablet to pc, my pen can drag the slider smooth as hell. but just one time fixed. if I click anyother window and come back to blender, the slider struggle again.

If I use the old tablet only, the blender slide is smooth.
as I only have one tablet with display. I dont know if it's an universal issue of just for Kamvas 22 plus.
so Let keep this session open.
my setting is enable windows ink and also make it in blender tablet API
