Have you tried adjusting the sensitivity settings on your FLIRC adapter to reduce the phantom keypresses? I had a similar issue with my setup, and tweaking those settings helped a lot. Also, have you considered using a different remote control to see if the problem persists?

It sounds like you've covered a lot of troubleshooting steps already. Considering the age of your remote, updating the firmware could indeed be the key. Have you checked for any firmware updates on the manufacturer's website? Also, trying a different machine without Steam or Logitech might help isolate the issue.
