I was happily coding when I noticed that a few pixels from some of my
sprites were just missing. After a lot of checking, I still can't find out
why. It happens always with the same bitmap data, and the same pixels.
Whatever the coordinates of the sprite on the screen, and of the bitmap in
vram, the missing pixels remain the same in every instance of the sprite
drawn.

The most intriguing fact is that if I scale up the sprite (say, 2*4096),
all the pixels are here! That means that the bitmap and clut in vram are
not damaged.

I ran my proggy on two different TV sets just to check, no difference.

I changed the background color (from black to dark and light grey) to
ensure it is not an illusion...

Has anyone ever met this? This is pretty weird... Any comment welcome!
(btw, if my description is unclear, please tell me so I can try and fix it
;) )
