SUMMARY I can reproduce this problem with Kdenlive, kolourpaint (both from flathub) and Ktorrent nightly (from kde apps flatpak repo). Not reproducible with the same apps installed from Arch repos. STEPS TO REPRODUCE 1. install any app mentioned above and open it 2. click on "Settings" menu, choose "Configure keyboard shortcuts..." 3. click on "Manage schemes >>" button > "More actions" > "Export scheme..." 4. type any name for your scheme and click on "Save" button OBSERVED RESULT shortcuts scheme is not saved, "Configure keyboard shortcuts..." window hangs and becomes unresponsive to mouse clicks. EXPECTED RESULT shortcuts scheme should be saved without any problem. SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 5.18.4 KDE Frameworks Version: 5.68.0 Qt Version: 5.14.2
I cannot reproduce, I tested with Kolourpaint and it saved the scheme correctly. What are your xdg-desktop-portal-kde and xdg-desktop-portal versions? Can you run "dbus-monitor --session" in terminal, try to export the keyboard scheme and kill the dbus-monitor and attach here the output?
I use xdg-desktop-portal-kde 5.18.4.1-1 xdg-desktop-portal 1.7.2-1 But weirdly the bug is no longer reproducible on my system. I will reopen this report and post the output of your command if the bug happens again.
