Are you loading those textures into VRAM (flag 256?) If not, try doing so; if doing it, try removing it...
But I still bet it´s a masked texture problem; try saving the texture with 0,0,0 as background, no anti-alias in the borders... and save it as 24bpp PNG or BMP, not JPG;
You could also try saving the texture as a PNG with alpha to see if it fixes the problem.
