description |
The MainView renders at the bottom-most layer a background composed of a colored rectangle and an image. The way it is currently implemented implies two fullscreen passes with alpha blending on. This is very slow. A solution would be to use just one pass using a ShaderEffect or a dedicated C++ component. Disabling alpha blending (possible since it's the bottom-most layer) would also provide a good performance boost. |

Another idea, if no image needs to be rendered, would be to simply set the GPU clear color to the background color, to render it for free. |
