The stack trace is identical to the one reported here. Hardware: AMD RX 9070 XT (RDNA4/Navi48), kernel 7.0.10-arch1-1, Mesa 26.1.1 Triggers (all XWayland applications): Disconnecting from a Citrix Workspace remote desktop session (100% reproducible) Closing Path of Exile 2 (Steam/Proton) Closing Zoom Closing Exiled Exchange Versions tested — all crash identically: KWin 6.6.4 and 6.6.5 Mesa 26.0.6 and 26.1.1 Vulkan renderer backend (KWIN_DRM_RENDERER_BACKEND=vulkan) Last KWin log entries before crash: kwin_wayland: User timestamp, final: KWin::X11Window ... "Tech Desktop (SSL/TLS Secured, 256 bit)" kwin_wayland: Denied set_cursor request from unfocused client kwin_wayland: Denied set_cursor request from unfocused client KCrash: Application 'kwin_wayland' crashing... The crash appears to be a null or dangling pointer dereference in Compositor::composite() when an X11Window is destroyed while a frame render is in flight. The libgallium worker threads visible in the coredump are blocked in pthread_cond_wait and appear to be bystanders rather than the cause.
