Windows 10 - Jerky Mouse Movement

Hi Arlen,

Hi, 
I have the same problem. 
The mouse (Trackpoint) feels like I'm fighting it (it's never done that) as well as the lag. 
I tried the solution that you recommended but I don't think it will solve the problem. The problem began after the last windows update on Monday night (Auguest 31, 2015) and it also happened 2 updates ago, as well. But the update between the two didn't cause mouse lag. It has something to do with the update and how it's allocating ram for different utilities. I'm also getting problems with YouTube (in Chrome). When I'm watching any Video they tend to freeze and sometimes when i'm typing in the addressbar (in Chrome) it is unresponsive. When I minimize and maximize the screen it then becomes responsive or it becomes completely unresponsive (program crashes). Also it tend to lag when I start typing faster than 60 wpm. 
It's a Windows 10 Update issue relating to Ram allocation as far as I can tell. I was going to rollback to the previous update but I disabled that feature. 
I have a feeling it will be fixed in the net update. 
if it gets fixed disable updates if it doesn't leave updates on until it gets fixed, then disable updates. 

My solution was to move the little Logitech USB receiving dongle for my "jumpy" mouse / keyboard (M310 / K520) to a different USB port on the back of my machine.

You have got to be kidding. I've read the instructions for "clean boot" and it's basically leaving me to do a detailed diagnosis of every possible interaction for dozens (hundreds?) of system software components.  I have no idea where most of these components came from, their names are generally meaningless and there's no way to tie them back to installed software.  99% of the software on my computer was there when I bought it and I have no way of knowing what is required by Lenovo to properly run, what is related to virus scanning, etc.  To say that this is a "solution" to a jerky mouse issue is ridiculous!

Microsoft needs to support, not just pass the buck.

Since Microsoft is leaving us to fend for ourselves, I'll add one note that might help someone discover what is going on - I've noticed that when Task Manager is running AND is the foreground window, the mouse suddenly becomes smooth, with no jerkiness.  If another window comes to the foreground, then the jerkiness returns.  So there is something about Task Manager taking control that eliminates whatever background service is running that causes the jerkiness.

I have noticed the same thing. When I am in Task manager or control panel, the mouse movement is fine. When I bring another screen to the forefront, the erratic movement returns. Still haven't found a solution. Is this a memory allocation for graphic driver issue?

I am experiencing the same problem and also believe it to be related to Task Manager. 

I have one thing to add in that I use dual monitors with my Lenovo Yoga 3.  The display/screen for the laptop does not have the jumpy mouse issue, only the 2nd monitor. 

I upgraded to Windows 10 about 10 days ago, but the problem appeared today when  I opened control panel and task manager.

I hope someone figures this out as it is killing my productivity.

This stuff happened with me as well.  What I did was to uninstall all windows updates after kb3081452. And the lag went away.  Everything It would install  an update it will become Jerky  and the moment II uninstalled it became fine. It is crude but it gets me by.  But please enlighten and share if there is a fix for this

I'm sorry, but you have a bug with your Operating System. My mouse was fine until the Fall upgrade. Now the mouse pointer "jumps" or lags. It is an ELAN Touchpad running the latest Windows 10 x64 drivers. Nothing I've tried works and I've tried your solution, reinstalling drivers, using just the ps2 driver, etc - to no avail. Also, interestingly - the problem clears up when task manager is in the foreground. I know my mouse has no problems because it works fine on the other OS on my computer - and it worked great until this last major update.

No issue at all while back upgrading from Windows 8.1 to 10 with all software installed intact.  But after upgrading again to ver. 1511, the mouse became jittery, and lag occurred with keyboard.  This applies to the Lenovo Helix for the on board keyboard, trackpoint, and all the various mouse and keyboards attached via a USB dock or its USB ports.

After another hour of upgrading the same OS, and after read up online for endless unless feedbacks and troubleshooting for days with uninstall and reinstalls, finally pop into my mind that sound card drivers could be the culprit.

On my Helix, the Realtek High Definition Audio driver dated 6/16/2015 version 6.0.1.7535 is installed along with an Intel(R) Display Audio.  In the start up, following are loaded:

"C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe" /FORPCEE4
"C:\Program Files\Realtek\Audio\HDA\RAVBg64.exe" /LENOVO_MICPKEY
C:\Program Files\Realtek\Audio\HDA\RAVCpl64.exe -s

By disable these 3 start ups in the Task Manager then reboot, the mouse and keyboard runs smoothly with no jitters.  No need to disable the sound drivers in Device Manager. There are no adverse affect on sound output in music or video playback.

Hope this information helps someone else.
