Qt Quick 2 was designed to take full advantage of OpenGL to make the most out of available graphics hardware. By not relying on OpenGL, Qt Quick 2D Renderer presents certain limitations regarding the available features.
Since Qt Quick 2D Renderer does not use OpenGL, there are some features that cannot be supported. The following are known limitations:
Qt Graphical Effects Module
Qt Graphical Effects uses ShaderEffect items to render effects. If you use graphical effects from this module, then you should not hide the source item so that the original item can still be rendered.
It is not possible to render particle effects with Qt Quick 2D Renderer. Whenever possible, remove particles completely from the scene. Otherwise they will still require some processing, even though they are not visible with Qt Quick 2D Renderer.
The Sprite item depends on inaccessible OpenGL functions and will not be visible.
The text rendering with Qt Quick 2D Renderer is based on software rasterization and does not respond as well to transformations such as scaling as when using OpenGL. The quality is similar to choosing Text.NativeRendering with Text items.
