Hi Alexander,
Yes, I also noticed this in the clutter reference manual. But no matter cogl_flush() is called or not, the results are the same. I think the frame buffer related operations in clutter_actor_paint affect this. I'm not so familiar with clutter, so I posted this topic here. :)
Regards, Jammy

With the sequence above, the actor cannot be displayed on screen. But if
I
replace clutter_actor_paint with raw gles2 rendering to paint a simple triangle, the triangle can be shown correctly. So I guess clutter_actor_paint didn't render to the new created fbo. is it related
to
the cogl fixed pipeline?
I was told that "after clutter_actor_paint to render the actor to texture (clutter/cogl) the next step is to call cogl_flush ()".
Have you checked that cogl_flush properly called in this case?
