Buttercup stays at about 40% CPU usage.
I don't know how to bugfix.
Confirmed.. Thanks for the report! Looking into it now..
Found the issue. It's the new about dialog. It had an uncontained useEffect react hook that was causing infinite re-renders. It'll be patched shortly.
This will go out in 2.0.0-r.5
Thanks. It's looking pretty good now that my fan isn't being loud. Good job.
