Nested light group slowness

I’m new to Home Assistant and discovered how to create light groups recently. My home office has eight can lights that I’ve added WiZ RGB WiFi bulbs to. I created a group for each of the four rows of lights, and then created a “All Office Lights” group that includes the four row groups.

Since upgrading to 2022.2.x (currently 2022.2.3), the automations (from an Aeotec Z-Wave Minimote) with the “All Office Lights” group has been extremely slow, taking over 10 seconds to complete. If I remove the row groups from the “All Office Lights” group and replace them with the individual lights, the response is instantaneous.

Going through the trace timeline, the Z-Wave signal from the Minimote is immediately received, but then there’s an almost always 10-second delay before the light changes on the nested “All Office Lights” group activates.

Any thoughts on why the nested group would be so slow in 2022.2? Am I doing something wrong?

Here’s what I have in configuration.yaml.

light:
  - platform: group
    name: Office Lights Row 1
    entities:
      - light.wizbulb_br30_basementoffice_1
      - light.wizbulb_br30_basementoffice_2
      - light.wizbulb_br30_basementoffice_3
  - platform: group
    name: Office Lights Row 2
    entities:
      - light.wizbulb_br30_basementoffice_4
      - light.wizbulb_br30_basementoffice_5
  - platform: group
    name: Office Lights Row 3
    entities:
      - light.wizbulb_br30_basementoffice_6
      - light.wizbulb_br30_basementoffice_7
  - platform: group
    name: Office Lights Entry Way
    entities:
      - light.wizbulb_br30_basementoffice_8
  - platform: group
    name: All Office Lights
    entities:
      - light.office_lights_row_1
      - light.office_lights_row_2
      - light.office_lights_row_3
      - light.office_lights_entry_way

You didn’t do anything wrong, i am having the same issue since the last update.
I am using groups to control on my lights and it is very slow to react, didn’t have this issue before.
Also if I try to control the light one by one it reacts immediately…
Hopefully there is a fix coming soon

Edit:
Issue seems open: https://github.com/home-assistant/core/issues/65885
