Forgive me if this has been posted before, but I seem to be having a strange problem with planet backgrounds being rendered. I'm usually playing a mod using the latest mediavp with no additional graphics or resource packages, for example, Homesick and the 3.6 MediaVP. Whenever I fly in the direction of a planet, sometimes it looks like it's segmented, or looks like it's pinched in the middle. This doesnt happen all of the time, sometimes the planets are rendered as round spheres, where sometimes they look like these. I've attached a really crude drawing of what the planets look like, as I am not at my computer with FS2_Open on it to do an in-game screenshot.

Currently I'm running the latest mediaVP that was released this month, and using the 04-05-2004 build of FS2_Open, running my mods in seperate folders.
Has anyone else encountered this problem, and may know how to correct it? or is it a bug that's already known and I'm posting old news?
