This is normal, and unless it is severe or does not go away when the engine warms up, there is nothing you can do about it, nor should you worry about it.
The clutch is bathed in oil that, when cold, is rather thick. The viscous oil between the clutch plates causes drag that tries to turn the driven plates even when the clutch lever is pulled (somewhat like a torque converter in an automatic transmission). This is completely normal. The thicker oil viscosity you use, the more you will notice. As the oil warms up, the symptoms should go away. If it is more than you like, drop your oil viscosity at your next change - like from 10W40 to 5W30.
