Slow mouse movement from 4k display to 2560x1600 mac

First thing is first, I made sure to update my synergy version to 1.7.6 and still has same issue. When my mouse is on my 4k Display PC and I switch mouse over to the Mac, the mouse works fine until I have to do slow movements. When I do slow movements with the mouse on the Mac it doesn't even move, and if it does move it jumps to another position, it is not smooth at all. At first I thought it was internet connection issue, because it seemed like it was laggy, but that isn't the case. If you need me to show u some type of debug or test let me know.
