Use a native QVulkanWindow child for Linux DMABUF presentation instead of making WebContentView itself a QRhiWidget. This keeps BrowserWindow on Qt's normal QWidget backing store path while sampling compositor DMABUF backing stores directly in Vulkan. Keep WebContentView's paintEvent as fallback for builds without Vulkan DMABUF support and for cases where the Vulkan instance or window cannot be created. Set an explicit Vulkan API version before creating the shared QVulkanInstance so validation layers do not reject Qt defaults.
