You need more colours.  This looks fine in 24bit on my work computer.  You
may be running less than 24bit colour.  Depending on the OS some video drivers
don't display a full palette of 24bit colour even though the driver claims
to be set to it.

So no, it's not jaggies exactly - it's your video card dithering the colours
down to what fits in your palette.
