Hey CC, like danielost, i've only seen this once, and it cleared after restarting the game. There was no battle (i'm familier with that effect), for me it happened after i created a game, went to the main menu, and started a new one with e different race (this is not reproducible). All of the polygon normals in the game were flipped, not just the planets, all the ships, stars, planets, etc... And they were all "stuck" that way, even when starting new games. However, as i said restarting the game corrected the issue. I did make a savegame to try and 'save' the problem, but upon loading the savegame, there was no problem. *shrugs*
