--- Comment #12 from aceman acelists@atlas.sk 2011-01-12 12:30:22 PST --- After trying bisecting mesa 7.9 and finally returning to the official snapshot, the problem vanished at the planet. It is still visible at some nebulas, but I am not sure it is the same problem. Both seem like a problem with some depth (distance from screen) determination.
