The longer pummelpuff runs, the less responsive it gets

[straach]

Hey confirm, thanks for the amazing tool that led to my project advancing really fast.

I use a setup mopidy + Spotify + pummeluff and the longer it runs the less responsive the RFID is. I am talking about "in the first 30 seconds.
GPIO for buttons stays relatively responsive, though often doesn't register a signal (play, pause).
It's really hard to say how responsive it really is and under which conditions, because it does not behave very consistently.
I get maybe 1 or 2 RFID consistent readouts and that's it. Now this afternoon I started it again and I got zero out of it.

I know the underlying library uses IRQ otherwise, I would think it gets stuck in the for-loops of pummeluff.

Any idea?
