Hi,
I’d like to share with you something strange happens when I use graphic pen.
Before everything, this is my setup:
KDE plasma 6.0.3
KDE Framework 6.0.0
QT 6.6.2
Kernel 6.5.0-26
Desktop Environment X11
Graphic pen Wacom Intuos Small
Now the issue.
The issue is that it seems that sometimes, for a reason I can’t catch, it records a single left click without release this click and, when I click on an opened program in the taskbar, it moves the previous program I’ve clicked on it.
As my spoken language is not English, it’s quite difficult to explain in a good way. I post a video of this.
Consider that, when you see the program icons move, I’m not holding the left click, I always made a point and click (and release). I hope it’s clear at least the issue.
If I use the mouse, everything is ok, so I’m quite sure that it’s something related to graphic pen driver…but if someone has some tips to help me on this, I’ll really appreciate.
This is the issue.
It seems that the Google video preview is broken. I suggest to download it to see what happening.
Hello,
I have this exact problem on my Arch Linux installation with KDE. Beyond the problem you say, I noticed other problems when grabbing and moving windows. I wrote a post on the Arch forums where I explain them, but I got no response so far.
I can add Leap 15.6 (plasma 5.27, X11, bare metal) fine
Neon* - (Plasma 6, obvs, Wayland, in Proxmox) seems like it is overly keen on debounce - and getting confused about if it has clicked or released - lots of selection areas were being dragged about and only releasing temporarily when clicking, only for the new selection area to “start” when I released pressure. couldn’t drag icons - seemed more
OpenSUSE TW (plasma 6, X11, in Proxmox): fine.
* However, I then booted back into Neon, and all was good. I don’t know if it had something to do with assigning the port in the VM while Neon (and the TW I tested) was running (although I assigned the USB to that while it was running too - neither machine had ever seen the CTL 490 (small Intuos) before) - rebooting and hotplugging made no difference - all is good now.
Worthwhile, but given this on a Manjaro forum, showing it to occur on both Gnome and KDE, I’m inclined to think the issue lies with the newer wacom driver, getting caught up on a state toggle (maybe debounce detection?) and it merely manifests itself on unfortunate people with specific hardware combo…
Maybe, if you have 2 different USB chipsets (little presumptuous, but I’m assuming everyone here is using USB tablets as opposed to a built-in i2c device) on board, (e.g. for front/back or left/right or manufacturer/reason) - swapping ports so you are using a different chipset (use lsusb -t to see) you might get some joy.
This is definitely a rare thing, but even if (as I suspect) it isn’t a solely-KDE thing, the devs that know the code from a KDE standpoint will have a better idea at a properly triaging it and pointing the finger with a more solid explanation than I can.
