Mouse cursor jumping when trying to indicate element

Hi all,

When I’m trying to indicate element on webpage (happens for all browsers) and I’m moving cursor to the element I want to indicate it keeps on jumping few cm left to right, front to back.

When I hit F2 it moves smoothly, but after 2 seconds it starts to jump around again.

Any ideas what might cause this problem or how to solve it?

Regards,
Rafał
