            Bug ID: 471202
           Summary: KDE authentication randomly starts failing and
                    characters while typing via physical and virtual
                    keyboard start multiplying
    Classification: Applications
           Product: konsole
           Version: unspecified
          Platform: Archlinux
                OS: Linux
            Status: REPORTED
          Severity: grave
          Priority: NOR
         Component: general

SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug
symbols.

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

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: approx. 1-2 week old
(available in About System)
KDE Plasma Version: approx. 1-2 week old
KDE Frameworks Version: approx. 1-2 week old
Qt Version: approx. 1-2 week old

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.
