I'm using CEGUI for UI system now. But when I try to run my game in full screen mode, the UI cannot be displayed correctly: they all become blank blocks.
So I switch to console to see what was going on. Then I find that the console keep print out those message:
FBO format unsupported
FBO error
FBO incomplete
again and again.
So what's wrong with that? My game can run perfectly in window mode, after all.
Any ideas? Thx
