SUMMARY I'm unable to use virt-manager and virtualizing Windows / other KDE Plasma and copying or pasting text. If I want to use clipboard, I have to close virt-manager or "hope" that next copy / past won't freeze keyboard. I had to jump to GNOME in order to do some virtualization... And I'd love to use Plasma ;-) STEPS TO REPRODUCE 1. install Debian Testing with KDE Plasma 5.14 2. install virt-manager and run Windows with Spice drivers of Ubuntu with Plasma 3. copy and paste text withing host or between host and VM (guest) or just in VM (guest) 4. keyboard freeze randomly stops working for approx 60 seconds when copy / past (it's random, sometime it's OK, sometime not) OBSERVED RESULT typing on keyboard does nothing EXPECTED RESULT keyboard should work SOFTWARE VERSIONS plasmashell --version plasmashell 5.14.5 dpkg --list | grep plasma ii kde-plasma-desktop 5:102 amd64 KDE Plasma Desktop and minimal set of applications ii kdeplasma-addons-data 4:5.14.5-1 all locale files for kdeplasma-addons ii libkdeclarative5 4:4.14.38-3 amd64 declarative library for plasma ii libkf5plasma5:amd64 5.54.0-1 amd64 Plasma Runtime components ii libkf5plasmaquick5:amd64 5.54.0-1 amd64 Plasma Runtime components ii libplasma-geolocation-interface5 4:5.14.5-1 amd64 Plasma Workspace for KF5 library ii libplasma3 4:4.14.38-3 amd64 Plasma Library for the KDE Platform ii plasma-dataengines-addons 4:5.14.5-1 amd64 additional data engines for Plasma ii plasma-desktop 4:5.14.5-1 amd64 Tools and widgets for the desktop ii plasma-desktop-data 4:5.14.5-1 all Tools and widgets for the desktop data files ii plasma-discover 5.14.5-1 amd64 Discover software management suite ii plasma-discover-common 5.14.5-1 all Discover software manager suite (common data files) ii plasma-framework 5.54.0-1 amd64 Plasma Runtime components ii plasma-integration 5.14.5-1 amd64 Qt Platform Theme integration plugins for KDE Plasma ii plasma-nm 4:5.14.5-1 amd64 Plasma5 networkmanager library. ii plasma-pa 4:5.14.5-1 amd64 Plasma 5 Volume controller ii plasma-runners-addons 4:5.14.5-1 amd64 additional runners for Plasma 5 and Krunner ii plasma-scriptengine-javascript 4:17.08.3-2 amd64 JavaScript script engine for Plasma ii plasma-wallpapers-addons 4:5.14.5-1 amd64 additional wallpaper plugins for Plasma 5 ii plasma-widgets-addons 4:5.14.5-1 amd64 additional widgets for Plasma 5 ii plasma-workspace 4:5.14.5-1 amd64 Plasma Workspace for KF5
