STEPS TO REPRODUCE 1. use Wayland session 2. open a chromium-based internet browser (used ungoogled chromium from flathub and Opera on my system) 3. load any website 4. drag the loaded url from the address bar and drop it on desktop OBSERVED RESULT chromium-based browser no longer reacts to mouse clicks. Restarting the browser does not solve the problem. I need to reboot or restart Plasma session to make the chromium-based browser usable again. Even an electron app (Discord) started after the steps above does not react to mouse clicks until reboot or re-login. EXPECTED RESULT the observed result should not happen SOFTWARE/OS VERSIONS Operating System: KDE neon Unstable Edition KDE Plasma Version: 5.24.80 KDE Frameworks Version: 5.91.0 Qt Version: 5.15.3 Graphics Platform: Wayland
In fact, all Xwayland apps (including Firefox) stop reacting to mouse clicks after the provided steps.
