SUMMARY Drawing tablets are not very usable on KDE Plasma. I don't know if this is Kscreen or Plasmashell or Wayland, please move it where it needs to go. STEPS TO REPRODUCE 1. Go to screen settings 2. Increase the scaling of the drawing tablet screen ( i set it to 125% ). 3. Restart OBSERVED RESULT The cursor is not alligned with the pen! EXPECTED RESULT It should be alligned! SOFTWARE/OS VERSIONS Operating System: openSUSE Tumbleweed 20250217 KDE Plasma Version: 6.3.0 KDE Frameworks Version: 6.11.0 Qt Version: 6.8.2 Kernel Version: 6.13.2-1-default (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 7700 8-Core Processor Memory: 30.5 GiB of RAM Graphics Processor 1: AMD Radeon RX 7900 GRE Graphics Processor 2: AMD Radeon Graphics Manufacturer: ASUS ADDITIONAL INFORMATION It's been like this for a long time. It makes scaling useless... My drawing tablet is a XP-pen Artist 13.3 Pro
Do you have any custom settings in drawing tablet system settings? I cannot reproduce the issue on my machine with 140% scaling factor
(In reply to Vlad Zahorodnii from comment #1) > Do you have any custom settings in drawing tablet system settings? I cannot > reproduce the issue on my machine with 140% scaling factor Did you reboot your system? I tried to change drawing table settings but nothing fixes it. The only thing that seem to temp fix it is to change back to 100% scaling, then increase it again. Then it breaks again once i reboot. But it doesn't fix it properly, the cursor is a bit offset so i fix it from the drawing tablet settings ( this is something i've noticed only today, so not sure how it works exactly yet ). I've noticed that it says 1536x864 inside the mapped area box, even tho in the screen settings it states 1920x1080. See screenshot: https://u.cubeupload.com/Azarilh/usdfgh.jpg

I've tried map to portion as well. Without being able to reproduce the issue, I'm afraid the bug report is not really actionable

See > screenshot: https://u.cubeupload.com/Azarilh/usdfgh.jpg The resolution text being different is an unrelated technical issue that shouldn't cause any problems. Relatedly, the mapping setting is stored in relative values (e.g. if you set it to half of your screen, it records "50%" - not "500px".) It wouldn't cause the cursor to be misaligned anyway.

This was not necessary to do without scaling, but at least it works now. I'll update this issue if i find more information that can help. I am not sure what could be different between our systems that makes it act differently, perhaps display brands. Would prolly need somebody else to report the same issue to figure it out.
Please stop moving the bug report to KScreen.
I am not doing anything.
Click "History" up in the top right corner and you'll see what happened.
(In reply to Nate Graham from comment #10) > Click "History" up in the top right corner and you'll see what happened. Huh!? I swear i didn't touch that at all.
It must have been an accident somehow.
It got worse for some reason. Now even with the settings that appeared to work for some days, don't work anymore. I recorded a video that shows the problem. Sorry for the bad focus of the video. https://www.youtube.com/watch?v=iKW_21ZPGUw No matter what i choose, even resizing the area, doesn't fix the issue, at most it becomes worse. Even after removing the scaling on the tablet, and rebooted, it still wasn't working... I just tried the calibration and it won't register when i touch on the bottom circles.
Well, installing the official XP-Pen driver made it work even better than before. Their drivers used to only work on X11, but apparently now they work on Wayland.
