I'm using SteamOS 3.7.8 (Xorg session) as the host and a distrobox-like container (https://github.com/alexsch01/distbox) that's running Fedora 42 / KDE Plasma 6.3.5 STEPS TO REPRODUCE 1. $ sudo dnf install plasma-desktop 2. $ startplasma-wayland 3. Press META+V to launch the clipboard history from host SteamOS's version of Plasma OBSERVED RESULT After I press META+V (host clipboard history popup) and clicked back to "KDE Wayland Compositor" window, - the keyboard acts weird, it thinks META is always clicked with every key - mouse clicking on buttons in applications doesn't work properly and on the window decorations' buttons SOFTWARE/OS VERSIONS Fedora 42 KDE Plasma Version: 6.3.5 KDE Frameworks Version: 6.14.0 Qt Version: 6.9.0

Can confirm. It's specific to the nested X11 backend though, the nested Wayland backend doesn't have this issue
