SUMMARY Plasmashell will crash when switching from the built in screen to the external monitor and vice versa using the screen switcher menu. STEPS TO REPRODUCE 1. Switch from built in screen(or external monitor) to the external monitor(or built in screen) 2. Plasmashell will crash OBSERVED RESULT Plasmashell crashes when switching screens EXPECTED RESULT Plasmashell does not crash switching screens SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.24.90 KDE Frameworks Version: 5.94.0 Qt Version: 5.15.4 Kernel Version: 5.17.9-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 8 × AMD Ryzen 5 3450U with Radeon Vega Mobile Gfx Memory: 5.7 GiB of RAM Graphics Processor: AMD Radeon Vega 8 Graphics Manufacturer: Dell Inc.
