            Bug ID: 474961
           Summary: Crash while selecting scrolling text
    Classification: Applications
           Product: konsole
           Version: 22.12.3
          Platform: Debian stable
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: charles at derkarl.org
  Target Milestone: ---

Application: konsole (22.12.3)

Qt Version: 5.15.8
Frameworks Version: 5.103.0
Operating System: Linux 6.1.0-11-amd64 x86_64
Windowing System: X11
Distribution: Debian GNU/Linux 12 (bookworm)
DrKonqi: 5.27.5 [KCrashBackend]

-- Information about the crash:
Note: this is not https://bugs.kde.org/show_bug.cgi?id=458822, because I'm
using a version newer than v22.08.3

I can reproduce this by:

1. Run a program that generates a lot of text in Konsole:

 while true; do echo $RANDOM; sleep 0.005; done

2. Have the machine be under a lot of CPU load

3. Consider nicing +20 the konsole process

4. Start selecting text as it scrolls by, move the mouse around like a psycho.

You may need to tweak the number "0.005"

The crash can be reproduced every time.
