      The stacktrace and webengine logs attached.

       

      Crash appears with all RHI backends "d3d11"/"opengl"/"software" (via QSG_RHI_BACKEND).

      Switching QTWEBENGINE_CHROMIUM_FLAGS="--disable-gpu" fixes crashes, the simplebrowser works.

       

      Issue doesnt reproduce on Qt 6.8.2
