Resolving a "stuck" pixel

There is a single pixel that always shows as red when activated. When the display is not using it, it is not red. I don’t think it is “stuck,” but I’m not sure if it is software (happens across apps) or hardware.

I also noticed some artifacts where adjacent pixels would illuminate the tidbit animation.

I have tried to use alternate power sources and reset the tidbyt. Any thoughts on how I can fix or can I send it in for repair/replacement?
