A500 ECS 1mb ... some glitches pic.1, pic.2 , and strange line pic.3 !!!
(Note: It happens the same also on AGA 1200 ... hm, maybe the dms is damaged ?!)
I don't know if the dms was damaged but when we take a look at the memory after demo was depacked, the picture is already damaged.
the damage seems to be the picture was dumped from memory after first execution : we can see the object blitted on it.
the only solution will be to find a "good" version of the file if exists, or the original picture from the author

I think that it is garbage from unused bitplanes. Picture uses less bitplanes than this demo defined. While clearing it clears parts of all used bitplanes. That's about first picture.

On second picture demo is using screen from first picture. There are at least 2 images on 2nd picture. Looks that they are using all defined bitplanes, but both images are smaller than defined bitplanes.

I don't know about lines on third picture. Maybe some leftover.

Did somebody tried to run demo on real Amiga?

garbage is from the "sun" bob
I picked each 5 bitplans and cleaned them one by one.
the bitplans 1 and 2 are clean
garbage start at the end of bitplan 3 and bitplan 4 and 5
