SUMMARY Applications using qtwebengine (say, kmail) unresponsive on startup when launched on Wayland with Nvidia without using XWayland (running with QT_QPA_PLATFORM=xcb). STEPS TO REPRODUCE 1. Launch Plasma Wayland Session 2. Launch Kmail OBSERVED RESULT Window is unresponsive, though process itself does not crash when launched via a terminal. EXPECTED RESULT Window accepts inputs and functions as expected. SOFTWARE/OS VERSIONS Linux/KDE Plasma: Fedora 40 release candidate/beta KDE Plasma Version: 6.0.3 KDE Frameworks Version: 6.0.0 Qt Version: 6.6.2 ADDITIONAL INFORMATION Output when run via terminal: qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "stateChanged" : Type not registered with QtDBus in parameter list: QNetworkManagerInterface::NMState qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "connectivityChanged" : Type not registered with QtDBus in parameter list: QNetworkManagerInterface::NMConnectivityState qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "deviceTypeChanged" : Type not registered with QtDBus in parameter list: QNetworkManagerInterface::NMDeviceType qt.dbus.integration: Could not connect "org.freedesktop.NetworkManager" to "meteredChanged" : Type not registered with QtDBus in parameter list: QNetworkManagerInterface::NMMetered DRM kernel driver 'nvidia-drm' in use. NVK requires nouveau. The reference to the specific kernel DRM driver is of note here, as programs without QTWebEngine do not have this issue nor display such a message.
I'm not able to reproduce this with KMail in a Wayland session on a laptop with an NVIDIA GPU. Plasma 6.3.2 Frameworks 6.11.0 Are you still experiencing this bug? If so, please set this back to REPORTED. Thanks!
