Currently, because the monitor I'm using supports a max resolution of 1280x720, and the CADR used a 768x896 monitor, and UHDL doesn't reset the VRAM read-out pointer until it hits the bottom of the logical monitor, the display effectively doesn't have vertical lock and continuously scrolls upwards (which wraps around). Currently this is useful so I can see the bottom of the screen, which has the loading bars, but it is still a bug that needs to be fixed once I find a better monitor.
