STEPS TO REPRODUCE 1. Login into KDE desktop (on kvm devices 2 out of 4) 2. Switch KVM to device 1 / 3 / 4 -- any other device connected to KVM. Wait 2 minutes 3. Switch back to KDE Neon device KVM device 2 out of 4. KDE is frozen for 60 to 80 seconds OBSERVED RESULT KDE Seems to forget that there was a device attached to it. This works without an issue on MX Linux (23.x) running KDE Plasma 5.x and MX Linux (23.x) running Xfce. EXPECTED RESULT Keyboard, Video output (hdmi) and Mouse should work immediately SOFTWARE/OS VERSIONS Windows: 11 22h2 macOS: (available in the Info Center app, or by running `kinfo` in a terminal window) Linux/KDE Plasma: KDE Neon (one with the bug) KDE Plasma Version: 6.3.4 KDE Frameworks Version: 6.13.0 Qt Version: 6.8.3 ADDITIONAL INFORMATION
