Hi jomax, I don't know what you mean by flickering reflections?
Can you post some screenshots or upload a video?

HOW TO PREVENT FLICKERING IN SMALL SCALE SCENES
If you are creating small-scale interior renderings, add a Standard material to your carpet, and adjust the Depth Offset slider in that material. Avoid extreme Depth Offset values - you should only adjust it a little bit, until the flickering stops (The best method is of course to make sure that your carpet is raised a bit above the floor in your 3D modelling application, so that the flickering is less likely to occur in the first place).

HOW TO PREVENT FLICKERING IN LARGE SCALE SCENES
If you are creating large scale exterior renderings, and you want to prevent models from flickering/disappearing when you move the camera far away, add Scene Effects -> Camera Clip Planes effect to the clip, and adjust the Near plane slider until the flickering is gone. You can also animate the Near plane if necessary by clicking on the small circular button to the right of the slider to set a keyframe.
