Description Ta-Lun Yen 2022-06-11 14:15:51 UTC 
SUMMARY

While KWin has implemented keyboard shortcuts inhibit (https://wayland.app/protocols/keyboard-shortcuts-inhibit-unstable-v1), similar needs for this still exists for application under XWayland (e.g. VMWare). GNOME has implemented this a while ago (https://bugzilla.gnome.org/show_bug.cgi?id=783342). 

Here's a reference to GNOME's implementation: https://gitlab.gnome.org/GNOME/mutter/-/commit/072afa5fa3e313e11e662c6a8fb291eda74e8766?expanded=1&view=parallel

Implement xwayland-keyboard-grab protocol

Only XWayland can see and bind to this global.
When a XWayland surface is focused that has a grab, shortcuts
are inhibited.

Sorry for reviving an old bug report, but this hasn't been fixed still happens on vmware and presumably other applications as well unless there is a way to enable it in the Windows Rules kcm which I haven't been able to find only the general shortcut inhibit not the grabbed input one.

I have attached a video demonstrating what I am talking about VMware grabbed the input yet when I hit the meta key it gets passed to the virtual machine.

Correction: The input gets passed to the host not the vm

Support was implemented; bugs in the support need to be reported separately, e.g. with Bug 502364.
