SUMMARY *** NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols. See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports *** STEPS TO REPRODUCE 1. Install AudioTube 2. Run OBSERVED RESULT No window shadows EXPECTED RESULT There are window shadows matching other apps SOFTWARE/OS VERSIONS Windows: / macOS: / Linux/KDE Plasma: Fedora Silverblue 38, Gnome/ Wayland (available in About System) KDE Plasma Version: / KDE Frameworks Version: 5.105.0 Qt Version: 5.15.9 ADDITIONAL INFORMATION I'm not sure if this is an app bug or upstream, since some Qt apps have shadows and some don't. If this should be reported upstream please kindly point me to it. Thanks!
Since GNOME doesn't implement client side decorations, so each app needs to draw this on its own. In the case of AudioTube that is done by QGnomePlatform. Please report it to them if you want to have it fixed.
https://github.com/FedoraQt/QGnomePlatform/issues/15 Looks like shadows will come in Qt 6!
