System exhibits uncontrolled screen-tearing that can be seen when moving windows, watching videos or playing games, or any graphical movement in general. The tearing gradually shifts up or down the screen, suggesting its a cycle frequency miss-match (or floating-point error).
Has affected mesa 12 and kernel 4.8 onwards.
