This happens to me intermittently, sometimes to the point of making my computer nearly unusable. Depending on my config and the computer's mood, it will affect either my external mouse or my external keyboard or both. Sometimes briefly, other times it's very disruptive for hours Happens wired and wireless. No one else at my company has reported this issue, but it follows me across work computers but does not happen with the same keyboards and mice on any of my 3 personal computers.
Work computers are all Windows 10. Personal computers I've tested with no issues include Windows 10 and Windows 11.
Typing this all out makes it seem like it may be the work config somehow, but we don't have any other users reporting this same issue.
I've been doing IT for 15 years and currently do tier 2 support for a medium sized company. I'm extensively familiar with troubleshooting and generally quite good at it, but like all humans I sometimes miss even obvious things.
Things I've tried:
Rebooting
Connecting only my keyboard and mouse and eliminating hubs and displays
Reinstalling drivers
BIOS updates
The LinkedIn Features suggestion from this thread
Using USB for both mouse and keyboard, or combinations: having the best luck with a wired keyboard and bluetooth mouse
A new computer: Two identical Dell Latitude 7420, and now a Dell Precision 5560, all importantly with the same standard config from my work
A new mouse: Tried a cheapo USB provided by work, a Razer Trinity Naga, a Logitech G502 Hero, and currently a Logitech MX Master 3 bluetooth mouse
A new keyboard: 2 decent quality USB-only keyboards (Razer and G Skill), cheapo work provided USB keyboard, and currently a Keychron that works over USB or bluetooth, connected via USB
Using wifi or a wired connection: currently connected via Ethernet with 250 mbps of bandwidth that I never approach
My mouse is so aggressively stuttery at the moment it's difficult to click the "Submit" button.
