heh i dunno why it does that (warning high quality pic - no 56k)

in screen, set it to 32 bit, not 16.

could be that dither is off too (or on.. i cant remember..)

Dither is supposed to be on/off when it's 16 bit and the opposite when it's in 32 bit...so really changing dither is all you need to do.

High quality.... Priceless

I remember having that problem when I played LFS once on a PC with Integrated Intel Graphics. I eventually came to the conclusion thats just how it is after trying to change everything.

You set your color depth to 16 bit, which is the cause for the slight green touch.

Color is build of three components red, green, blue. So if you calc 16 / 3 you get 5 bit, 5 bit and one times 6 bit. The 6 bit is assigned to green, because this is the most sensible color for the human eyes.

Guess a 50% grey for smoke
Red 5 bit --> 32 possible color levels, 50% --> 15
Green 6 bit --> 64 possible color levels, 50% --> 32 (graphic card will div this by 2) --> 16
Blue 5 bit --> 32 possible color levels, 50% --> 15

Notice green is slighly higher then the other colors. So with 16 bit the color can't be an exact grey like smoke should be.

To prevent the 32 bit / 3 question :-) :
Red 8bit
Green 8bit
Blue 8bit
Alpha Channel 8bit
