changeimgpart+changecoloreffect
 

If you showimg, changeimgpart, then changecoloreffect, something weird happens - it shifts the changeimgpart coordinates up one. It also refuses to shift back down, ie if you're trying to get at the bottom 16x16 of a 16x32 image,
changeimgpart 0,0,16,16,16;
changecoloreffect 0,1,1,1,0.5;
will give you the image from y=15 to 31 instead of from y=16 to 32! It does this even when you don't use changeimgpart - it will just "invent" another line at y=-1 and shift your alphablended image down by one pixel. Case in point, splashscreen.graal on classic - maybe it's just me, but every time I go there, it fades in...then *pop*, down one pixel.

Yeah i seem to have that problem too.
I tried having my ASD Stats transperant but it shifts the image because thats just what the setimgcolor does....
I dunno why.
