Hmmm. The problem we are seeing is with Linux drivers on 64 bit
machines (EMT), not on Windows. Cells seem to get random alpha values.
What happens when you turn off immediate mode rendering? Also try
changing the value of "Interpolate Colors" (which switches between
using 1D texture maps and using OpenGL interpolation).
