Sentry Crash Report:

Description Andrew 2022-10-09 17:04:19 UTC 
Application: plasmashell (5.25.5)

Qt Version: 5.15.6
Frameworks Version: 5.98.0
Operating System: Linux 5.15.0-48-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User - 5.25
DrKonqi: 5.25.5 [KCrashBackend]

-- Information about the crash:
Oh, wow, I don't know how much good information I can offer :( This is an automatic bug report and I'm just filling in some information.

I use a portrait-landscape-portrait monitor configuration, driven through a combination of Display Port cables (including a daisy chain) connected to a CalDigit TB3. I connect my 2017 HP Spectre x360 (Intel Graphics) to the CalDigit TB3 using a CalDigit ThunderBolt 3 cable (and recently, a ThunderBolt 4 cable).

I've found KDE Neon to be incredibly buggy with my setup (I know that's amorphous and non-descriptive), so I actually plan to move to another distribution. I think there's just poor support for my odd display configuration.

Generally:
- disconnecting my laptop from the dock crashes/freezes Plasma, requiring a hard reboot
- connecting my laptop to the the dock crashes/freezes Plasma, , requiring a hard reboot
- the login screen flickers when using the laptop

The crash can be reproduced sometimes.
