Jax Classic Frames Taint Issue

[Nonamexxy]

hey,

I currently use the addon Jax Classic Frames which causes a lot of lua errors/actionbar taints lately.
The actionbar taints always occurs when switching between the talent loadouts.
LuaError:

AddOn 'ClassicFrames' tried to call the protected function 'UseAction()'.
[string "@!BugGrabber/BugGrabber.lua"]:480: in function <!BugGrabber/BugGrabber.lua:480>
[string "=[C]"]: in function `UseAction'

I did some testing and found the following function is causing the error respectively to be more precise the line: self.playCastFX = false;. Uncommenting/deleting this line fixes the error but the player castbar glow effect is not removed.

local function HookSetLook(self, look)
    self:SetStatusBarTexture("Interface\\TargetingFrame\\UI-StatusBar")
    if ( look == "CLASSIC" ) then
        self.playCastFX = false -- ERROR CAUSE
        self:SetSize(195, 13)
        self.Border:ClearAllPoints()
        self.Border:SetPoint("TOP", 0, 26)
        self.Border:SetTexture("Interface\\CastingBar\\UI-CastingBar-Border")
        self.Border:SetSize(256, 64)
        self.BorderShield:SetTexture("Interface\\CastingBar\\UI-CastingBar-Small-Shield")
        self.BorderShield:SetSize(256, 64)
        self.BorderShield:ClearAllPoints()
        self.BorderShield:SetPoint("TOP", 0, 28)
        self.Text:ClearAllPoints()
        self.Text:SetPoint("TOPLEFT", 0, 2)
        self.TextBorder:ClearAllPoints()
        self.TextBorder:SetPoint("TOPLEFT", 0, 0)
        self.TextBorder:SetPoint("BOTTOMRIGHT", 0, 0)

    elseif ( look == "UNITFRAME" ) then
        if (self == PlayerCastingBarFrame and PlayerCastingBarFrame.attachedToPlayerFrame) then
            HookOnEventTarget(PlayerCastingBarFrame)
        end
    end
end

hooksecurefunc(PlayerCastingBarFrame, "SetLook", HookSetLook)
PlayerCastingBarFrame.type = "player"
PlayerCastingBarFrame:HookScript("OnEvent", HookOnEventPlayer)
PermaHide2(PlayerCastingBarFrame.Background)
PermaHide2(PlayerCastingBarFrame.Flash)

Is their a safe way to disable the playCastFX/player castbar glow effect for PlayerCastingBarFrame without tainting my actionbars ?
Thank you in advance!
