Application: kwin_wayland (6.3.2)

Qt Version: 6.8.2
Frameworks Version: 6.11.0
Operating System: Linux 6.13.5-200.fc41.x86_64 x86_64

DrKonqi: 6.3.2 [CoredumpBackend]

-- Information about the crash:
I get 7 crash reports by the system, each slightly different. As I do not have enough experience to figure out which one of them is most significant, I report them and let whoever can sort out which one is.

I have a system with Dell 7470 laptop, its docking station and to the docking station connected a Dell UltraSharp UP2716D via Displayport.
From the displayport output on this monitor, there is another monitor Dell U2413.
This setup has been working for years with fedora + KDE plasma.
On updating today (haven't done it for a few days, so updates from perhaps 25th of february onwards may be included), on initial reboot the screens go black after a few initial screens (shows Dell on bootup and fedora booting).
When I disconnect the external screens I can log in to KDE plasma as normal on the laptop built in monitor.
I can then connect the UP2716D (without the U2413 connected) and it will show the extended desktop.
When I try to connect the U2413 within a couple seconds all screens go black and stay so for a while.
Now it seems to be a little unclear, what happens next.
Sometimes I get a login / desktop unlocking prompt after a while, but if I log in everyting immediately goes black again.

(I have similar problems on a second computer too, a Dell 7400 with two Dell U3219Q monitors connected via a Dell USB-C/Thunderbird docking station, but that is not in this report. Just to indicate that it seems to be happening on two sets of completely different hardware.)

The crash can be reproduced every time.
