A yellow key is a 'Stuck Key'—it is sending repeating signals without being physically pressed. This usually points to debris in the switch or a mechanical failure requiring cleaning or replacement.

Hold multiple keys at once (e.g., W+A+Shift+Space). Check the 'Pressed now' counter. If you are holding 4 keys but only 3 are showing, your keyboard has hit its ghosting limit.
