Cursor greatly retarded!

After reinstalling of Linux (Mint 17 Cinnamon 64 bit) and DraftSight the mouse pointer is so strongly delayed on the work space of DraftSight that DraftSight is unusable.

In the menus the pointer behaves normally. 3D - driver (Geforce GTX 750 Ti) is active, 3D games work.

Who knows what to do?
