#this draws a magenta ellipse:

c = Ellipse(size = (200,279), pos = (220,118))
        
with self.fbo:
    Color(1,0,1,1)
    c
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
    Rectangle(size = (640,480), texture = self.tex.texture)

#this doesn't:

c = Color(1,0,1,1)

with self.fbo:
    c
    Ellipse(size = (200,279), pos = (220,118))
    glBlendFunc(GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA)
    Rectangle(size = (640,480), texture = self.tex.texture)
