Windows 10 mouse pointer pause/stutter and audio crackling issue.
Things tried so far in the order done, and their result.
1) Searches indicate that it can be fixed by un-ticking "Enhance pointer precision" in the "Motion" section of the "Pointer Options" tab of "Mouse Properties" in the original version of "Control Panel".
This appears to work so far, the clicking audio also appears to have disappeared with this one change.
I'm still not convinced, and I'll update this after a day of use.
To do this, click "Search" on the task bar, and type "control panel" in the search box, then click on the result to open up "Control Panel". Click on "Mouse" in "Control Panel", and then click on the "Pointer Options" tab now you will see the tick box for "Enhanced pointer precision" just under the pointer speed slider. Remove the tick from the box and click "OK" at the bottom of the window.
Now do the things that used to make the mouse stutter and see if the issue still exists.
