I have a SB3 connected to a Surface Dock which has FullHD touch monitor, USB keyboard and mouse connected to it. I have used this setup without any issues for over 2 years with Surface Laptop 1.
With the SB3 the keyboard and mouse 'stutter' meaning characters are lost or autorepeat due to missing down or up codes. Mouse motion ceases then resumes.
I have a video of the mouse re I continuously move the mouse in a circle

I have tried plugging the mouse into one of the SB3 USB ports and get the same result.
I know others have seen this problem. It should be easy to reproduce. Can someone from Microsoft try this please.
This looks to be a level USB message handling problem. Note that the USB is not unloading.

If this does turn out to be an effective temporary fix, would someone mind listing all the instructions together? All of the steps are kinda scattered throughout this discussion, and I won't wanna miss any and screw up my computer any more than microsoft already has lol
