Whilst more than likely you are using a kernel with a known incoherency bug (as there is yet to be a kernel release with it fixed), the effects are quite different to the ones you captured. The issue which I believe to be behind the distorted flickering can be quite easily triggered by simply changing the number of rectangles submitted in a single draw call. In practice, this then both depends upon the exact details of the rendering and its timing.
