Can you provide a list of each physical input device you own? Also, are any of these wireless devices that share an RF receiver? e.g. a pair of keyboard + mouse that both use the same USB receiver.

I'm sorry, can you clarify what kind of list would be helpful? Those are all wired USB devices. I've tried plugging devices into my laptop and I see same behavior there too.
Like, can you tell me what physical mouse and keyboard devices you have plugged in at the time the bug occurs?

My daily drivers right now are Corsair K70 rgb mk.2 (keyboard) and Logitech G102 mouse, on additional screenshot Razer Viper 8k and Razer DeathAdder V2 also connected.
Thanks! Can you paste the output of `lsusb` while these devices are plugged in?

What's happening is that your devices are inappropriately reporting themselves as multiple mice. This might be a bug in the devices themselves, and it might be a bug in Libinput, but it's not the problem of our KCM. I'd recommend reporting it to Libinput, along with the output of `libinput list-devices` that shows the issue.

Hi Nate, while true, devices do report themselves as multi-capable, I don't think that mouse kcm should show devices that are not mouse. Looks like currently there is patern search for capibilities for "pointer", hence Razer Razer DeathAdder V2 Keyboard also shown in a list, as it's reported as "keyboard pointer".

Yeah, looks like we can do some of this ourselves.

Git commit c35939966f964d90c25ad38ce26d343bfaf191a4 by Nate Graham. Committed on 09/04/2024 at 21:56. Pushed by ngraham into branch 'master'. kcms/mouse: also filter mice that say they're keyboards When enumerating devices to identify mice, the KCM already filters out pointer devices that say they're touchpads. But it doesn't do so for devices that say they're keyboards. This is weird, but apparently a lot of gaming mice report themselves as multiple devices with one being a keyboard that has only a couple of buttons on it. Let's filter these out so that we only see the mouse representation of these devices in the KCM.

Unfortunately that approach had to be reverted as it regressed the ability to find weird gaming mice that report themselves exclusively as being both a mouse and a keyboard. Xaver and David E have a better idea though; see https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2183#note_929752. In the meantime, I'm re-opening this.
