mouse blinking between dual monitors bug

since I re-instaled windows ONLY when I open Krita on my tablet the mouse is moving between both screens.
To give more of a perspective, let’s say both my screens are 1280x1080.
Let’s call X axis 0 between both screens Positive Y axis main screen and negative Y axis the tablet screen.
If I put my pen on the tablet tablet at X: 720 and Y:-720 it will blink constantly on Y:-720 (tablet) and Y:720(main monitor), it doesn’t move between, it just blinks as if I was using one mouse on two monitors.

Things I tried:
-Rollback.
-changing tablet to main monitor.
-use only one monitor (Had to try, of course it works but the idea it’s to fix the dual monitor :P)
I’ve looked into the configs but couldn’t find anything that could help me.

Edit:
uploaded videos POV
main screen tablet: clean install.

main screen the screen: clean install.

Update:
Tablet I use: Artisul D13s
I used this with no problems before, it happened after I had to re-install windows.

This sounds like the tablet driver loads an application specific profile when Krita starts, where the screen mapping is different. Some tablet drivers detect when a graphics (or other) software starts and do this. Try to set up a custom profile for krita in you tablets settings manager, where the screen is mapped correctly to the tablet, or change the one the driver has created automatically if possible. Or try resetting the tablet to screen mapping while Krita is running so the driver updates its (possibly hidden) profile.

Edit: I read it wrong, as the mouse would move across both screens but it still sounds like a broken tablet configuration that is loaded by the tablet driver when Krita starts (since Krita itself doesn’t control your Cursor position). The steps I mentioned could still help.

Sounds like a windows ‘mirror’/‘extend’ monitor issue…check your windows setup under ‘system’

On a little update, When I move Krita to the main monitor it doesn’t blink.
I tried having Krita on half of the tablet screen and only on the Krita Window it blinks between screens

Tried custom tablet profiles on the settings manger but they didn’t make any difference
(Wintab tried 3 mappings, tablet provided, entire virtual screen, map to custom area and there tried diferent numbers)
Tried mapping with the tablet driver with Krita closed and Krita open.
Tried reinstalling Krita
Tried reinstaling the tablet driver

Still testing I found this only happens when I try to use the tablet, Krita is on my tablet screen (it doesn’t matter if is second or main screen) and the pen (mouse) is on Krita.
If it’s more helpful I can make a recording showing the issue.
But as the mouse blinks between screens is a 50% chance to click on Krita so I don’t even try to draw. (If I’m not mistaken tablet settings only affects drawing correct me if I’m wrong as I’m not sure)

I have no Idea what could cause this. Krita doesn’t get to control the position of the mouse cursor. Is it really only happening when Krita is running? The only thing I can think of is the hardware acceleration feature. Try changing canvas acceleration in Krita from OpenGL to Angle or vice versa or deactivate it completely. I could imagine that a broken graphics driver could cause issues but basically your guess is as good as mine.

Yes, it only happens when Krita is running and I have my pen over Krita :confused:
Tried changin canvas accelerations and deactivating it. No changes
Also tried doing a clean install of the graphic card, no changes :frowning:

This is a super weird issue. Last thing I can think of, something I read on another topic about a totally different issue, is (since it worked before) is that the newest drivers are defective but you didn’t notice since you didn’t update them before the new install on your old windows. After reinstalling you naturally installed the latest drivers but they are bugged while before you set up a new windows you had older ones that where still okay.

This happened to another user here but in their case it was even worse because the manufacturer stopped supporting their device in the meantime (had a similar issue once too where they accidentally swapped x and y access in a libwacom release). So my last idea would be trying older versions of the tablet driver. Speaking of which, have you tried installing previous versions of krita to check if it happens there too?

Tried the rollback version (Steam version) : Same error.
Tried Page recent version: Same error
Tried 32-bit just in case: Same error.
4.4.3: Same error
4.4.2 (Iast version I used): Same error?
Will try to re-install the last windows update and try all over again…

Try using a slightly older version of the tablet driver. But I’m out of ideas. Controlling the cursor is usually the operating systems responsibility together with the hardware and peripheral drivers. I have no idea how Krita could interfere with the cursor.

Have you also tried deleting the Krita configuration files, thus resetting the configuration?
After all, reinstalling Krita does not change the configuration files. The configuration files are located in the folder “c:\Users{YOUR WINDOWS USERNAME}\AppData\Local”, where you have to replace the expression “{YOUR WINDOWS USERNAME}”, including the braces, with your username (your login name) in Windows, so if you login with “DrakoSenpie” (without the quotes) in Windows you would have to put that there, and as long as those files are not removed there, Krita will keep using those old configuration files.
You can either backup the following files to another location (then you would have a backup of your settings, if this was not the issue), or delete them completely to reset Krita’s configuration (since you seem to have “abandoned” it already (so much for reinstalling everything to get back to the original state)):
kritarc.backup;
kritarc;
kritadisplayrc;
kritacrash.log;
krita.log;
and the Krita directory (if it exists there)

This would give you Krita “reset to zero”.

After updating windows this is what happened.
If tablet is main screen when the pen is outside the Krita window is working perfect. But when I move the pen inside the Krita Window the Y axis is diferent. (For example if I have the pen on Y = 720 inside the krita window will be Y = Y+200)
Tried: deleted the complete folder from APPDATA and reinstaled, same with older versions.
I uploaded 2 videos to show how my POV
main screen tablet: clean install.

main screen the screen: clean install.

Not hopeful Update:
I don’t think it is the tablet driver as it works perfectly on other programs (paint, photoshop, adobe animate, etc…)
For extra info: They released versions until 2020 for my tablet (Artisul D13s)
Anyway, I tried an older version and it made it all worst. The tablet wasn’t even working with the older version of the driver.

Fixed the issue! I’ve been having this for a bit, but thanks to Takiro’s inital comment about the mapping, I was able to troubleshoot the issue and find a solution.

To fix: open Krita, go to settings (on the top bar), click “Configure Krita”. Select “Tablet settings” and click the bubble that says “Windows 8+ Pointer Input (Windows Ink)”. Restart Krita and you should be good!

It’s funny I tried like 10 times this before and didn’t work. (And now somehow it did)
But been testing all over again and this time it worked after re-installing the tablet driver.
So this time was a mix between a bad tablet driver install which (maybe?) had a corrupt file and a Krita Setting. On normal cases this should be the solution but I still find it weird that it didn’t work for me between yesterday and today until I reinstalled all, even windows :’).
One thing I can be sure is to never rollback again my artisul tablet driver.

Anyway anyhow.
It’s now fixed and I want to thank everyone for their time

Yea, i probably should’ve mentioned I did a clean reinstall of multuple versions of krita and my tablet drivers before switching to the windows ink input, but yay we figured it out!
