V98.0.2 Phantom Keystrokes

Making moves

After updating to 98.0.2, Firefox starts registering Down Arrow key with no physical input. This issue only occurs in Firefox, but will persist for a short time in Windows after closing/minimizing/unfocusing Firefox.

I've done the following troubleshooting steps:

  1. Uninstalled all keyboard devices in Device Manager and restarted
  2. Uninstalled Logitech GHub
  3. Unplugged the Keyboard
  4. Started Firefox in Safe Mode
  5. Scanned with Malwarebytes + Windows Defender
  6. Refresh/Reinstall Firefox
  7. Ran System File Checker

Any suggestions are greatly appreciated, this issue has made the browser practically unusable. Typing this out has been challenging.


Making moves

To update, Opera has the same issue, but Edge doesn't. Perhaps I have a corrupted Driver after-all.

Found the issue is caused by a separate input device I failed to check, oops.
