Release with the issue: V1.10.9 Last working release (if known): N/A Browser and Operating System: Chrome 107.0.5304.87 on Ubuntu 22.04 Chromium Browser Version 98.0.4758.141 (Developer Build) Built on Ubuntu 20.04, running on Ubuntu 22.04 (64-bit)

Description of problem: When focused, dashboard with single slider-button-card causes cpu to run at 24+%, compared with 5-12% for other dashboards. A view with 10 slider-button-cards uses around 40% cpu. I'm pretty new at using Chrome performance tools, but when I record the page just sitting there, it appears that it is repainting when it doesn't need to. This problem only occurs when the "show_spinner" attribute is set to "true".

About every 15ms, it appears the same task is executed:

Here's the dashboard yaml: `title: Vango views:

• theme: Backend-selected title: Lights Slider path: lights-slider icon: mdi:light-recessed cards:
  • type: custom:slider-button-card entity: light.lights_kitchen name: Kitchen slider: direction: left-right background: gradient use_state_color: true use_percentage_bg_opacity: true show_track: false toggle_on_click: false force_square: false show_name: true show_state: true compact: true icon: show: true use_state_color: true tap_action: action: more-info icon: '' action_button: mode: custom icon: mdi:power show: true show_spinner: true tap_action: action: toggle `

The entity's state hasn't changed, so there shouldn't be any repaints needed.
