Cursor Jump Problems

If you have the same problem try this:
For Windows

1. (First try this)
- Press the Windows Key + R
- Search for Tablet PC Input Service
- Right click on it, Properties - Make sure that on Startup it's set "disabled"

(You will need to reboot your PC after you have tried the step above.)

2. (If that didn't work, try this)
Turn off enhanced pointer precision
- Open "Control Panel"
- Click "Mouse"
- "Pointer options"
- Uncheck "Enhanced pointer precision"

If this doesn't work, do you have a Pen Tablet installed? Or any similar?
If that is the case, then you need to make sure ALL the Pen Tablet programs are off. Because they interfere with WoW.

So you can either uninstall them or open "Task Manager" and temporarily shut them down.

If you happen to have Shadowplay, disable it and restart your computer.
Because that is what caused this bug for me most recently. [Oct 2014]

This seems to have fixed the issue for me, personally. I have windows 7 and this generally only happened in World of Warcraft, but after disabling that service and restarting I haven't had the issue re-occur.
