Cold start gearbox

Hello together, I noticed during the last season at the R8 that after a cold start the start of the journey is a bit difficult as if the clutch would grind, so if I operate the accelerator pedal the speed increases but the drive is felt at 30%. If I wait after the cold start until the increased speed re-enters normal, this problem is no longer present and I can start normally. Is this problem worrying or a special feature of the G drive? I could live with it but would like to fix this if possible. V10+ Year of construction 2013 approx. 40tsd km Thanks and greetings Chris
