I didn't see any screenshots but I guess you mean random crap in left border? Many demos and games have accidental crap there because borders are partially hidden when using regular television. They are usually only visible when using 1081/1084 or any other TV monitor with adjustable screen size or position, or emulation :)* Video emulation is a bit off for TV modes like PAL. There are artifacts and odd rendering outside the viewing area. I don't know what is causing this.
