How to undo "opera:fps" power setting inOM7

Last post by rafaelluik: There needs to be a power making the image to stay on the screen, so even if it's static the graphics card needs to be continuously sending the rendered image to the screen. I don't know the specifics but the thing is that images don't get out of the graphics card after they "take shape", so it's still there occupying the capacity in some way (Maybe even being re-rendered? IDK. I mean if you had an opportunity to measure the FPS of a game running on your PC, even if you pause the image like go to menu or pause control in simulation games, the image will look the same but FPS will continue to vary). And phone displays also have frequency (Hz).
Another detail is how Opera isn't the only software using the device's resources, Android system itself and other apps may also keep the CPU/GPU busy, making the FPS vary.
