Comment 14 for bug 1225944

I was able to repro with Shevonars hint. The reason is that terrains are not saved with alpha channel internally and there was a false assumption that then alpha = 255, which it apparently only is for opengl. I attempted a fix in r6782.

I think (but am not sure) that the OP's bug is fixed with this as well. Could all of you check this please?

I'll wait for a few days, and when I hear nothing I'll suggest a date for the winter time feature freeze.
