Go to SolutionSlow motion mouse on desktop - XPS 15 9550
I'm finding when the mouse is scrolling on the desktop its extremely slow - like slow motion. If there is a window like Microsoft Edge taking up some desktop space then the mouse cursor will speed back up to normal again but as soon as it goes back to desktop its slow motion.
Its severely irritating. I have a top spec XPS 9550 running Windows 10.
Anyone know what the problem is? is a display driver issue? It happens sometimes not all the time.
thanks a lot oupablo. I think its definitely NVidia related. I closed all open Nvidia related task in task manager and that solved the issue. I will try and pin point exactly which task is the offending one.
you were certainly more helpful than Dell Robert P. Reinstalling the OS is always a last resort instead of more constructive means to resolving a software problem.

From the link, here is the specific advice you seek:
Keyboard, touchpad, or mouse not working correctly
This article provides troubleshooting steps for Mouse, Keyboard and Touchpad issues such as:
The cursor movement is not smooth (erratic) or does not move at all.
The cursor moves around erratically while typing.
The scroll wheel has erratic movement or is not moving the page.
Robert P (retired)No Robert, none of the solutions for those symptoms work, I'm using the latest touchpad drivers, in fact all the drivers are the latest for the XPS 9550.
The trigger is the start menu. When the start menu is brought up and the mouse cursor moves over the open start menu across to the desktop, the moment it transitions onto the desktop the mouse movement goes slow motion, with severe lag. As soon as the cursor hovers back over the open start menu, it speeds back up again to normal....

Obviously at this point it appears to be a software issue. Have you tried reinstalling your Operating System? According to your post, it occurs when the Start Menu comes up, so that leads me to think that the OS may need to be reloaded.

I have the same system as you.
This appears to be caused by the Dell Premier Color app. In TaskMgr, it was showing 1718MB of memory (over 1GB!) in use, and the mouse cursor was slowing down when moving across the desktop background - but fine when moving over TaskMgr.
My guess is that it's part of the window-manager code which is busted, as it'll hook all of the underlying window messages going through the input stack in the OS.
Killing the app reverted the system to normal behavior. So my guess is that it's that. You could try uninstalling it and reinstalling it from the downloads site, but I don't know if that will fix it :)

So this may be way to late to help you, but I was experiencing the exact same issue. What managed to fix it for me, at least so far, was going to the Startup tab in Task Manager and disabling Nvidia Catpure Server Proxy. I disabled it, restarted and everything seems to be working again.
