SUMMARY The meta key will be captured by all desktops STEPS TO REPRODUCE 1. Use remmina's rdp to remotely connect to windows in workspace 2 and use full screen. 2. Move the mouse to the toolbar at the top of remmina to enable grab all keys. 3. Press the desktop grid shortcut and use the mouse to switch to another desktop. 4. Press the meta key or the shortcut key containing meta. 5. Switch to the desktop where remmina is located. OBSERVED RESULT A pop-up menu pops up on the remote windows desktop. EXPECTED RESULT When switching to another desktop and pressing meta, the remmina on desktop 2 no longer receives meta,windows no longer pop up menu. SOFTWARE/OS VERSIONS Windows: 11 macOS: Linux/KDE Plasma: Archlinux (available in About System) KDE Plasma Version: 5.22.4 KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION Remmina does not have this problem on gnome, so I think it may be a problem with kde. If it is not, I am sorry for my mistake.
I know that wayland has fixed the problem of remmian and other software grabbing all the keys, but I found that when the mouse leaves the window of the remote system and presses the meta key, the remote system can still grab the action to make a pop-up start menu, etc. Xorg also has the same problem, but xorg can’t grab all the keys. I only tested the problem on remmina. I think it’s not a problem with remmina because it works fine on gnome.
