The command happily reports that everything is fine:
First one is the physical double-press to get home, the second one is the round Home button.
Code:

I have suspicion that App Optimization from Onyx might be the culprit. When com.onyx was enabled, I optimized the e-ink launcher.
Let me disable it and try again.
