Hi all,
i have an issue with draw something inside a fbo. I draw a red circle in the fbo. Later i wanted to draw a green circle inside the fbo. It is drwan correctly but when the circle is overlapping the old red one it is drawn behind. I also tried to call ofClearAlpha() after the last drawing but the same result.

Any help would be nice.
