之前在3.4.2里，可以用这样的方法同步截屏，不用等到下一帧:
let renderTex = new RenderTexture();
renderTex.reset({
width: 1024,
height: 1024
});
this.m_camera.node.active = true;
this.m_camera.orthoHeight = 512;
this.m_camera.targetTexture = renderTex;
// director.root?.pipeline.render([this.m_camera.camera]);
director.root?.frameMove(0);
let sp = new SpriteFrame();
sp.packable = false;
sp.texture = renderTex;
但是在现在3.6.2里，完全没有效果，请问该怎么同步截屏呢?
