Slow mouse move for second system user on NVIDIA driver

I have two system users, and for first login to plasma, everything is ok, but when I open second x session, mouse cursor is slow and laggy. Its after install nvidia proprietary driver for cuda/opencl operations. I install drivers from rpmfusion repository.

Fedora 31, Nvidia driver version: 440.100
On radeon card or nouveau driver is everything ok.
How can I resolve this issue?

Best regards!
