SUMMARY I started Marble 25.08.3 in Plasma 6.5.3 on Wayland in a Fedora 43 KDE installation. When I closed Marble by clicking at the top-right of its window, Marble crashed. Dr. Konqi appeared, but it couldn't create a trace because the core dump hadn't been created yet. Marble crashed with the error "Failed to restore OpenGL context after clean-up." in QtWebEngineCore::ScopedGLContextForCleanup::~ScopedGLContextForCleanup () at /usr/src/debug/qt6-qtwebengine-6.10.1-2.fc43.x86_64/src/core/compositor/native_skia_output_device_opengl.cpp:84.
