...or whatever you want to call it. Usually everything except the units gets really dark and the game slows way down. Sometimes, just for variety, I presume, the units turn black (particularly noticeable with ships). This problem has been reported in this forum by a lot of users with all kinds of machines using all kinds of CPUs. Saving and reloading seems to fix it temporarily, but it always comes back. Just wondering if anyone has figured out what causes it and if it's been officially recognized as a bug which needs to be patched.
