SUMMARY

I've been using Krita for a few times now and everything alayw worked perfectly till now. I recently change my computer (just the computer itself, not the tablet itself and when trying to use krita after a few days, I exeprienced something strange.

First, as I was working on a drawing, if I clicked on another program (multi screen setup) then back to Krita, it was confuse and thought that I was still using my mouse. I tried specified to krita to only work on my tablet monitor and it seemed to resolve the problem for a while.

But after a day, Krita continued doing this even with the specified area assigend to krita (my tablet monitor) and even weird, it stop recognizing my tablet as such.
When going into the configuration of Krita, when I test the pen pressure it doens't show the pen, it consider it as a mouse everytime I trace something.
It only tells it's a tablet pen when I move the pen away and close to the tablet but as soon as it toucht the screen, for krita it's a mouse.
I even tried to enable/disable the pen pressure with the icon in krita but noting seemed to work.

I'm using a huion tablet, Kanvas GT-191 and I had no troubles before changing my computer for work.

I've tried to see if the tablet drivers was up to date and it is, I even tried an older tablet driver but none of this worked. It's a fresh new config and I installed the same things as on my last ones so I don't understand why it suddenly stop working.

I really loved Krita and I'd like to have it back to work with.
I had to use another art program and my tablet works really fine with any other program I use, don't know if it's relevent.

I've mailed Huion about this. We're getting quite a few complaints about Huion lately, but there actually is no code that directly talks to tablets in Krita. You might want to update to the latest version of Krita (4.4.3, released last week), though, since that has a workaround for issues that happen when you switch between windows.

I actually already update krita this morning and no change, still the same problem. I hope huion will find what's wrong, please let me know if you got any answers.

I cannot find what's wrong, because it's not something I can reproduce, and worse, it's not something we can fix in Krita's code. Krita does not actually contain any code that directly works with tablets, so people who have issues with their tablet, especially on windows are always having an issue with their setup, yes, even if only Krita is affected.

You can:

* try to reset Krita's settings (https://docs.krita.org/en/KritaFAQ.html#resetting-krita-configuration)
* try to reset the tablet driver's settings
* try switching between wintab and windows pointer api

but we cannot do anything for you.

Hi,

Huion has asked me to ask you to contact them:

Please mail service@huion.com with the following information:

* Version of our tablet driver they've installed

* OS version you are using

* Serial number of your tablet

* Krita version
