STEPS TO REPRODUCE
1. Install Arch Linux with minimum packages on a machine (I used ThinkPad T440s if that matters)
2. Set it up
3. Try using it for longer and eventually two strange things with start happening:
  - Authentication will fail, when doing sudo, or sudo -i, even when copy-pasting the correct password
  - Characters will start repeating itself while typing i.e. when you click e once 5x e will appear. It seems to not consistent with all letters and is probably pseudorandom. Funnily enough, when connected thru rustdesk the same thing happens as if I was using the physical keyboard, so it's definitely a KDE issue.

OBSERVED RESULT
  - Authentication will fail, when doing sudo, or sudo -i, even when copy-pasting the correct password
  - Characters will start repeating itself while typing i.e. when you click e once 5x e will appear. It seems to not consistent with all letters and is probably pseudorandom. Funnily enough, when connected thru rustdesk the same thing happens as if I was using the physical keyboard, so it's definitely a KDE issue.

EXPECTED RESULT
- Authentication succeeds each time when typing correctly and copy-pasting the password
- Single typed characters are not being multiplied

ADDITIONAL INFORMATION
How do you debug this? I probably need to deliver more information, but I'm not sure which one do you actually need. Funnily enough the bugs get fixed by a reboot, but that can't a be permanent solution...

I recently updated my OS and looking whether this persists or it was fixed.
