Before Plasma 6, keystrokes like the break key or super key would go to the virtual machine if VMware had focus. Now, Plasma is executing them first. For instance, if Plasma has a shortcut for the break key and so does the VM, Plasma will execute its shortcut when pressing the break key while in the VM. The super key is a little different. If I press the super key while in the VM, both machines open their launchers.
It seems like a bug. Is this new behavior the default? Is there a workaround?
