            Bug ID: 469289
           Summary: Can't open any KDE applications after connecting an
                    external display
    Classification: Applications
           Product: konsole
           Version: 23.04.0
          Platform: Archlinux
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: konsole-devel at kde.org
          Reporter: justynboyer at gmail.com
  Target Milestone: ---

Application: konsole (23.04.0)

Qt Version: 5.15.9
Frameworks Version: 5.105.0
Operating System: Linux 6.2.11-arch1-1-t2 x86_64
Windowing System: X11
Distribution: "Arch Linux"
DrKonqi: 5.27.4 [KCrashBackend]

-- Information about the crash:
After plugging in an Anker A8365 hub into a DELL P2217 monitor, I recieve
crashes upon trying to open any new KDE applications. Other QT apps (like
qBittorrent and qalculate) open. Any apps opened while the display is connected
result in a crash report by Dr Konqi. After disconnecting the display, KDE apps
can then be reopened. This behaviour doesn't happen when the hub is connected
to my laptop without the display. Any ideas?

I'm using a custom linux kernel for a MacbookPro16,3.

The crash can be reproduced every time.

-- Backtrace:
Application: Konsole (konsole), signal: Segmentation fault
