I have found a temporary solution below for this issue. But I am not sure if there will be any side effects. - do not call cogl_flush() after paint_func(actor) in ctk_effect_xxx_paint() functions - do not call ctk_effect_set_invalidate_effect_cache() after render to cached texture in ctk_effect_xxx_paint() functions
