What exactly do you mean with "clipping"? This word means that parts of an image is being cut off, but there was no change in OBS in the last years that made OBS cutting things off just by applying an update.
Probably, you did change something in OBS configuration that made things look unexpected. Your scenes could go havok if you change the base resolution (Settings->Video), or if you change the Windows desktop resolution or the resolution of your game you capture.
