We have multiple monitors on multiple computers. 2 Computers and each have 3 monitors attached. Since updating to version 3.5, if we change the Display scaling above 100% on either Primary or Secondary computer then the mouse button clicking causes the mouse to jump all round the secondary screen. Mouse movement from primary to secondary is not effected only the mouse clicks on the secondary. Changing the scaling back to 100% fixes the issue. We have tried rebooting computers to no avail. We are using Windows 10 and Dell PCs with additional video cards installed. Previous version seem to handle this before without issue.
This may have more to do with the mice attached.
If you have the software for the mouse installed (Logitech, Razor, etc) and you scale the polling \ DPI way down, does that change it? If you plug in a generic mouse, does that change it?
