Problem taking a copy of the screen

Hi,
I’m was taking a copy of the screen this way:

texture = Texture()
base.win.addRenderTexture(texture, GraphicsOutput.RTMCopyRam)
base.graphicsEngine.renderFrame() 

Sometimes i have text on screen and i don’t want it on my texture. I can’t hide the text before that on put it back later because i don’t want the user see the text desapearing for a moment. What can i do? There is a way to capture only render?

Thanks!
