ClutterOffscreenEffectget_texture

Retrieves the texture used as a render target for the offscreen buffer created by effect

You should only use the returned texture when painting. The texture may change after Clutter.EffectClass.pre_paint is called so the effect implementation should update any references to the texture after chaining-up to the parent’s pre_paint implementation. This can be used instead of clutter_offscreen_effect_get_texture() when the effect subclass wants to paint using its own material.
