Snes9x 1.51, strange motion effect

[Xirix]

In Snes9x 1.51 there is a motion-ripple effect that shouldn't be happening. Example below.

http://www.youtube.com/watch?v=MIcb9MPA5kg at 9.25 onward, notice the wooden planks in the platforms, it looks like vertical 'scan lines' are appearing as the auto-scroll moves the screen.

Anyone know what might be causing this? And if simply updating to 1.53 would fix it?

you're outputting at a resolution that's not an integer multiple of the native resolution, and therefore have inconsistent displayed pixel sizes.

as for your second question - just try it.
