I have a logitech G810 keyboard experiencing severe keyboard chatter. The fix will limit the rate of the keyboard and is not suitable for gamers.
Registry patch for Windows. The patch applies the fix to the current user and the default "user" (the user for Windows login screen).
The fix introduces a 40ms debounce period and a minimum of 10ms period to hold down a key to accept the keypress. This might break some macro functionality that sends keystrokes without delay between keystrokes or a hold down delay (KEY DOWN followed immediately by a KEY UP without delay).
The patch has only been tested on Windows 10.
