SUMMARY *** The 8.1.0 appimage has no titlebar under Wayland. *** STEPS TO REPRODUCE 1. I tried launching with: QT_QPA_PLATFORM=wayland ./Applications/digiKam-8.1.0-x86-64.appimage In the log output I see the messages 'unknown: EGL not available' and 'unknown: Unhandled container to remove : Digikam::DigikamApp' 2. I then tried launching with: QT_QPA_PLATFORM=wayland-egl ./Applications/digiKam-8.1.0-x86-64.appimage Digikam failed to launch. 3. I then tried: QT_QPA_PLATFORM=xcb ./Applications/digiKam-8.1.0-x86-64.appimage Digikam launched normally, with a titlebar. OBSERVED RESULT When run without amendment the appimage creates a window without a titlebar. EXPECTED RESULT The appimage should run without modification under Wayland and create a window with a titlebar. SOFTWARE/OS VERSIONS Ubuntu 23.04
I can use the AppImage here under openSUSE in a native Wayland session without any problems, the title bar is available. Setting the QT_QPA_PLATFORM environment variable with wayland, for example under X11, leads to an error message with every Qt program. I think I've read this problem before on Ubuntu, also with other programs, since Ubuntu removes the title bar, there was some other thing that needed to be set. If I find it I'll post it here, otherwise I won't pursue the bug any further. Maik
Thanks for the response. I am running a Wayland session. I am running other appimages without issue: BambuStudio_ubuntu-v01.07.02.51-20230804223010.AppImage kdenlive-23.04.3-x86_64.AppImage UltiMaker-Cura-5.4.0-linux-modern.AppImage Bob
I can also deactivate the title bar for the respective program under Plasma. Such a setting may be stored in your window manager. In Plasma it would be Alt+F3 to get to the window settings, it will probably be a different shortcut in Ubuntu. In digiKam we do not anything special with the title bar other than setting a title. Maik
It's a good thought and the same occurred to me, but having tried all the shortcut combinations I could think of and resetting the Digikam config files, I haven't been able to find any setting that's hiding the titlebar. I installed KDE system settings to see if there was anything there, but the dialogue is all but empty as I have no KDE components installed. Also, I have since concluded that it couldn't be this: 1. I've never had KDE/Plasma installed on this system. 2. The app has a titlebar when launched with QT_QPA_PLATFORM=xcb I think (2) strongly suggests that this isn't a misconfiguration on my system.
Are you using Gnome? Gnome Wayland doesn't support server-side window decoration and instead expects the application to provide window decoration. Qt provides a plugin system for doing such client side decorations and comes with a default implementation (called bradient) Those plugins are in /usr/lib64/qt5/plugins/wayland-decoration-client/ Most likely the appimage is missing such a plugin and thus no decoration can be created
Yes I'm using Gnome on Wayland. That does sound like it might be the issue. I was aware there are some differences in the way Window decorations are handled under Wayland but didn't know the details, thanks for the explanation.

I've just tried the linked 8.2 appimage, it still launches without a titlebar I'm afraid.
Can you check if this appimage has the same dysfunction ? https://binary-factory.kde.org/view/AppImage/job/Digikam_Nightly_appimage-centos7/
Inconclusive, that one doesn't even want to start on Ubuntu (23.10) I'm afraid: ``` ./digikam-master-381-linux-gcc-x86_64.AppImage -- digiKam Linux AppImage Bundle -- Use 'help' as CLI argument to know all available options for digiKam application. -- Notes: to integrate this bundle to your desktop, use AppImageLauncher. -- to enable all debug messages on the console, use 'export QT_LOGGING_RULES="digikam*=true"'. -- Detected host Linux ubuntu-64-23.10 -- AppImage mounted directory: /tmp/.mount_digikaHnSI0k Check library libudev.so.0 Check library libxcb-dri3.so.0 Check library libcrypto.so.1.1 Check library libssl.so.1.1 Check library libnss3.so Check library libnssutil3.so Check library libsmime3.so Check library libpango-1.0.so.0 Check library libpangocairo-1.0.so.0 Check library libgmodule-2.0.so.0 -- Preloading shared libs: :/usr/lib/x86_64-linux-gnu/libxcb-dri3.so.0:/usr/lib/x86_64-linux-gnu/libnss3.so:/usr/lib/x86_64-linux-gnu/libnssutil3.so:/usr/lib/x86_64-linux-gnu/libsmime3.so:/usr/lib/x86_64-linux-gnu/libpango-1.0.so.0:/usr/lib/x86_64-linux-gnu/libpangocairo-1.0.so.0:/usr/lib/x86_64-linux-gnu/libgmodule-2.0.so.0 digikam: symbol lookup error: /usr/lib/x86_64-linux-gnu/libpango-1.0.so.0: undefined symbol: g_string_free_and_steal Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome.
