This actually marks some data as "dirty". Makes one wonder what the point of pre-allocating a large number of vertices then is, since it seems that you can just as well stick to changing the counts to the needed number. Anyhow, last time I asked wrt the color corruption: "what if you also manually set the vertex color for each vertex?" Either you didn't try or didn't tell anyone the results. -f.r.
