Cannot detach the keyboard when I switch to other virtual desktop.

[zhaodice]

Distro: https://launchpad.net/ubuntu/+source/virt-manager/1:4.1.0-1/
Bug Step:
1.the virt-manager uses the mouse/keyboard alone in FULLSCREEN (catch all of the mouse/keyboard event)
2.leave the virtual machine by shortcut key
3.use KDE's hot corners to switch others virtual desktop
4.keyboard doesn't work,what I have typed will be redirected to the virtual machine but I have exited it, and virtual machine window is in the other virtual desktop.

Thanks for the report. Can you follow the debugging steps here to help narrow down what config is involved: https://github.com/virt-manager/virt-manager/wiki/Debugging-VM-graphical-display-issues

I reproduced the same problem with virt-viewer win10 --attach, I guess it is the "Spice GL/Virtio 3D support graphical issues" because I passthough my NVIDIA and vGPU , Enable OpenGL with spice

but when I move mouse to show the top tool bar, and press Ctrl+F8 to switch virtual desktop, the bug is gone, the bug is only emerged when I switch virtual desktop by hot corners

This could also be a KDE bug potentially, if it's only reproducing with a non-standard config, but you'd want to confirm with multiple VM graphics configs first. Would be interesting to see if the issue reproduces without GPU passthrough too.

Either way it doesn't sound like this is virt-manager specific. If you narrow it down more you can try filing a bug against spice-gtk: https://gitlab.freedesktop.org/spice/spice-gtk

yes, it is interesting, when I use QXL (without OPENGL and passthough), problem is disappeared. of course, I have to passthough GPU...
