Near whites in fullscreen = transparent

[DustyPorViva]

I know Graal uses pure white and black as transparent(even though I wish this was dropped), so I try to avoid them with near-whites and blacks when I make graphics. It's all well, and the whites and blacks look fine and aren't transparent normally. However, I rarely do... but I tried out fullscreen and it seems that they are being rendered transparent instead. This is breaking nearly all my graphics and I can't lower the white values anymore without changing the look of them alltogether, and it would be a pain to go through ALL my graphics and replace the whites and blacks.

So ya...
