Sentry Crash Report:

Description Diogo Duarte 2023-05-19 14:02:31 UTC 
Application: plasmashell (5.26.0)
 (Compiled from sources)
Qt Version: 5.15.7
Frameworks Version: 5.99.0
Operating System: Linux 5.15.0-71-generic x86_64
Windowing System: X11
Distribution: KDE neon User - 5.26
DrKonqi: 5.26.0 [KCrashBackend]

-- Information about the crash:
I don't have much information, the KDE crash handler noticed the issue before I did. Apparently after I pressed enter on sddm to open up the system after sleep, plasma crashes. Sometimes (this is not consistent, sometimes it happens, sometimes it doesn't and I don't know how to exactly reproduce this), the panels from the 2nd monitor (not primary but the main laptop screen) are placed on the first monitor (primary monitor, HDMI external screen).
I'm ticking "KDE Platform is compiled from source" only because I'm using Kubuntu but with the KDE Neon repositories and plasma's most recent version (that is available for 20.04 LTS). It isn't actually from souce but I had no other way of signaling this.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
