X11 Unmanaged Window
SUMMARY
STEPS TO REPRODUCE
1. Open VMware workstation 17 on Kwin wayland.
2. Run Windows or Linux in VM.
2. Press shortcuts which combined with Win, Alt.
OBSERVED RESULT
The host task switcher grabed shortcuts first, the VM grabed it again.
EXPECTED RESULT
Keyboard grab should be inhibited in host. VM grab the shortcuts.
SOFTWARE/OS VERSIONS
Arch Linux 6.1.11
Linux/KDE Plasma: 5.27.0
KDE Plasma Version: 5.27.0
KDE Frameworks Version: 5.102.0
Qt Version: 5.15.8
ADDITIONAL INFORMATION
Keyboard xwayland protocol didn't be added in kwin 5.26.5. So the shortcuts in
vmware or freerdp(X11) can't be grabbed correctly. For kwin 5.27, the shortcuts
feature was added, so freerdp (X11) can grab shortcuts correctly.

However, the same issue existed in vmware.
I think it may caused by the X11 unmanaged window. Xwayland can't handle the
unmanaged key grab correctly? https://linux.die.net/man/3/xgrabkeyboard
VMware workstation has two windows: GTK UI and VM virtual desktop. The GTK UI
was managed by X11. But the VM window was unmanaged.
