It's probably a rounding error, isn't it?

((h-1) * (w + (alignment - (w % alignment)))) + w

Moreover, it's up to you to pass the right size for the newly created buffer.

 ((888 - 1) * (587 + (4 - 587 % 4))) + 587 = 522143

It seems to work for me.

Are you sure that you pass the right "type" and the right "depth" to GLBuffers.sizeof()?
