I tried reinstalling it twice, the second on another drive, and it still happens.... I'm assuming that it has to be a specific setting, because i don't think a bug wouldn't be so persistent.

Yes. I check compile, light and link. I don't think that would be the problem since it happens inside the level editor as well.

Default. From the first time I opened radiant.

There's a video for A.P.E here

Hope it helps.

I did that. This is the result of that. I'm wondering if there is a setting i need  to have or something.

My lighting is a bit weird, shadows are very dark and you cannot see anything in them.
