SUMMARY
When I disconnect my laptop from a dock with two monitors attached and at least
one browser is open (I'm often running firefox and/or chromium), kwin_wayland
crashes and so do my browsers.
Nothing crashes if I disconnect without a browser open. Using the dock with a
single monitor
STEPS TO REPRODUCE
1. Connect two monitors to my dock and connect the dock to my laptop.
2. Open a browser (steps 1 and 2 can occur in any order).
3. Disconnect the dock from the laptop.
OBSERVED RESULT
kwin_wayland crashes and so do my browsers
EXPECTED RESULT
Everything stays open and shifts to the laptop screen.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.4.4
KDE Frameworks Version: 6.17.0
Qt Version: 6.9.1
Kernel Version: 6.16.3-arch1-1 (64-bit)
Graphics Platform: Wayland
Processors: 16 × AMD Ryzen 7 7840HS w/ Radeon 780M Graphics
Memory: 32 GiB of RAM (30.7 GiB usable)
Graphics Processor: AMD Radeon 780M Graphics
ADDITIONAL INFORMATION
Similar to several other issues (508620, 505759, 502951) but the stack traces
and behaviors seem different enough that I don't think they're duplicates.
PS I don't know if there's a way to get details that are optimized out. I'm
happy to produce a different backtrace or whatever if it would be helpful.
