    Description

      Steps to Reproduce issue

      • Create a custom qml item in root qml view.
      • Use FastBlur qml item from graphic effects and set the source as the custom item.
      • Construct C++ type deriving from QQuickItem and make it available to custom qml via registration using qmlRegisterType.
      • Construct C++ class deriving from QSGNode and implement QSGNode::render function to render using metal render pipeline function with pixelFormat as MTLPixelFormatBGRA8Unorm.
      • Set render interface to Metal Rhi
      • Execute qml application.

      Actual Result:

       Application crashes on start of execution with the following error:

      For color attachment 0, the render pipeline’s pixelFormat (MTLPixelFormatBGRA8Unorm) does not match the framebuffer’s pixelFormat (MTLPixelFormatRGBA8Unorm).
