PROBLEM : Characters have white shadows.

TROUBLESHOOT:

1. Non-buffered rendering actually removes your shadow and makes big shadowy black blocks under your feet.
2. Buffered rendering gives you white shadows.
3. Read framebuffers to memory (CPU) removes your shadow, and DOES NOT give you the shadowy black blocks.
4. Read framebuffers to memory (GPU) ^

So I'm unable to find a SOLUTION. I want normal shadows, and no graphical glitch.

Maybe the solution is in another option?
