With BL_VKBRIDGE_CEF_ANGLE=vulkan the CEF GPU process stopped crashing but Chromium still composited in software (gpu_compositing: disabled_software, Steam "Disabling GPU acceleration: Disabled/RuntimeDetect", VizCompositorThread at a full core). The GPU report shows why: "eglCreateWindowSurface failed with error EGL_BAD_CONFIG". ANGLE's Vulkan backend on X11 gives every EGL config the root window's visual; Chromium's X11 surface asks for a config whose EGL_NATIVE_VISUAL_ID is the ARGB visual whenever a compositing manager owns _NET_WM_CM_S0 (gamescope does), finds none and passes a null config. bl_webhelper_layout() now adds +Vulkan +VulkanFromANGLE +DefaultANGLEVulkan for ANGLE on Vulkan, so Skia composites through an xcb swapchain on ANGLE's Vulkan device and no EGL window surface is needed. BL_VKBRIDGE_CEF_VULKAN=0 leaves it off; unset BL_VKBRIDGE_CEF_ANGLE still means Steam's stock layout.
