SharpenAI 3.3.1 using CPU/GPU when idle

Just noticed on my MacBook M1 Pro SharpenAI is using up to 52% GPU, 60% CPU from having just opened it, not even loaded an image. It also causes WindowServer to use GPU too so its hitting about 75% doing absolutely nothing.

Is this some weird Rosetta 2 bug?

Happens on current Gigapixel using Apple Silicon too, if I leave the app open long enough (granted were talking days but as I have a dedicated Mac Mini for this I tend to leave the app open) it will eat an entire CPU core and make the UI unresponsive. I had to force power off last time as I couldn’t even reboot over SSH.
