            Bug ID: 451401
           Summary: Random but related crashes
           Product: Akonadi
           Version: unspecified
          Platform: Archlinux Packages
                OS: Linux
            Status: REPORTED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: server
          Assignee: kdepim-bugs at kde.org
          Reporter: vikts at pm.me
  Target Milestone: ---

Application: akonadiserver (5.19.3 (21.12.3))

Qt Version: 5.15.3
Frameworks Version: 5.91.0
Operating System: Linux 5.16.13-zen1-1-zen x86_64
Windowing System: Wayland
Distribution: "Arch Linux"
DrKonqi: 5.24.3 [KCrashBackend]

-- Information about the crash:
If I play a game long enough (Xwayland), suddenly all Xwayland applications
crash and cannot be restarted. When trying to restart it, there is no output in
commandline, it just hangs.

Yesterday, I had systemmonitor (ctrl+esc) crash every time when trying to
resize or right click in it. It started working normally after the xwayland
applications crashed.
It was crashing with the following output:
kde wl_display at 1: error 1: invalid arguments for wl_shm at 61.create_pool
The Wayland connection experienced a fatal error: Invalid argument

Today, that weird crash was preceeded after some minute of Plasmashell
constantly crashing and restarting after I got a notification.

These issues seem to be completely random, happen since 5.23 at least and it is
the first time DrKonqui launched and it is the first debugging information I
managed to get out of these crashes.

Removing all Plasma .config files did not stop the issue from occuring.

The crash can be reproduced sometimes.
