I use a KVM to switch my monitors between two different inputs (This PC and a work laptop). When I switch back from my laptop to this PC, Quickshell crashes regardless of the PC being locked or in suspend.
I have a service set up which automatically restarts Quickshell if it crashes on display connect, so other than the crash dialog, nothing is out of the ordinary. But, before I set up the service, the screen would sometimes be completely blank and I'd have to restart the PC.
