Limit Kodi UI FPS at all times, not just playing video back

  • Is there any way to lock max frame rate of the user interface?

    I have a Raspberry Pi 3B+ and while it is pretty good, it often seems to be quite fast in the UI, then slow at other times.

    Locking it to say a solid 20fps period, may result in the feel being more consistent.

    Can this be done?
