Hide GCD blink on action bars

[junior whale]

Good morning, I have a lua code that hides some action bars (including the main action bar):

local function configActionBars()

  -- Avoid interaction with action bars
  local bars = {
    "ActionButton",
    "MultiBarBottomLeftButton",
    "MultiBarBottomRightButton",
    "MultiBarLeftButton",
    "MultiBar5Button"
  }

  for _, bar in pairs(bars) do
    for i = 1, 12 do
      local button = _G[bar..i]
      if button then
        button:SetScript("OnEnter", nil)
        button:SetScript("OnClick", nil)
      end
    end
  end

  -- Hide the main action bar and specified additional action bars at all times
  MainMenuBar:SetAlpha(0)
  MultiBarBottomLeft:SetAlpha(0)
  MultiBarBottomRight:SetAlpha(0)

    local function HideSelectedActionBars()
        if MainMenuBar:IsShown() then
            MainMenuBar:SetAlpha(0)
        end
        if MultiBarBottomLeft:IsShown() then
            MultiBarBottomLeft:SetAlpha(0)
        end
        if MultiBarBottomRight:IsShown() then
            MultiBarBottomRight:SetAlpha(0)
        end
    end

  local f = CreateFrame("Frame")
  f:SetScript("OnUpdate", HideSelectedActionBars)

end

The problem is that, as you can see from the attached video, the GCD keeps showing at every GCD. How can I modify the above lua code and fix this? Thanks in advance!

Hide GCD blink on action bars

[weak trail]

I myself simply set my bars alpha to 0 and don't have this. You can inspect those frames with /fstack or VDT and see if you need to hide something else there

Besides that: f:SetScript("OnUpdate", HideSelectedActionBars)

you're running your script there every frame

which is completely unnecessary obviously, and bad for performance. how come you do it like that?

well, in the first place it's completely unneeded to create a frame in WA. you can simply execute your stuff in the on-init of some random aura

Thanks for the reply. I've tried putting only this code:

MainMenuBar:SetAlpha(0)
MultiBarBottomLeft:SetAlpha(0)
MultiBarBottomRight:SetAlpha(0)

but still get the same behaviour. At every GCD there's this blink
