Descriptive Problem Summary:
- I've noticed a problem but now sure if its just me but I took notice just recently that areas out of bounds of the game and blank /turf locations just turn up as white areas when using the blend functions to do lighting when you turn up the alpha on the darkness plain.

Expected Results:
- Out of bound areas and blank turfs(/turf) should not show up in white and should be black at all times.

Actual Results:
- White areas show up when you turn up the alpha on the darkness plain.

Does the problem occur:
Every time? Or how often?
- Yes
In other games?
- Not sure
In other user accounts?
- Yes
On other computers?
- Not sure

Change the color of your master_plane from white to black.
The plane master already is black.

This is quite puzzling to me. If SEE_PIXELS is in use, those empty squares should be covered by black tiles. If it's not, they should be transparent, but your master_plane should be converting all its transparent areas to black.

Although this shouldn't be necessary, as a workaround you could add another darkness image to plane 0 with BACKGROUND_LAYER. That ought to at least give you a backdrop for the missing tiles.
SEE_PIXELS is in use so I'm not sure what's up. I'll try your work around method when I get home.
I'm also curious what happens with SEE_PIXELS turned off.

Also, this may be a stupid question but do you have a client color set?
Tried your method and still comes out with the same results, there is defiantly something up. Took off SEE_PIXELS and still looks the same. I believe I do not have client color set.

Tried out Nadrews Lighting Test and came out with the same results. http://www.byond.com/developer/Nadrew/LightingTest

Also on a side note apologies for the picture extending out words I did not notice it until now.
Have you made sure your graphics drivers are fully updated?
Yea all up to date. I do not know whats up at this point but it is strange.
