When I put a color board on the timeline it stays its original color for about 5 seconds then gets rendered automatically and turns to the color red. It is only happening in my current project. The two screen shots explain. The first screenshot was taken immediately after placing the color board on the timeline. The second screenshot is about 5 seconds later.
