[Resike]

My pet frame resets to default position unless I add PetFrame.SetPoint = function() end No taint log so far, ToT frame stays where I placed it in combat, so far so good. Does anyone know a better way to keep my pet frame stationary? I tried SetMovable and SetUserPlaced, they didn't work, PetFrame kept resetting. It's working fine with SetPoint = function() end, so far at least, but if this is something that causes taint I'd like a better way to lock my pet frame in place.

Hook it, as Seerah mentioned:

local moving
hooksecurefunc(PetFrame, "SetPoint", function(self)
    if moving then
        return
    end
    moving = true
    self:SetMovable(true)
    self:SetUserPlaced(true)
    self:ClearAllPoints()
    self:SetPoint("CENTER", UIParent, "CENTER", 0, 0)
    self:SetMovable(false)
    moving = nil
end)
PetFrame:SetPoint("CENTER", UIParent, "CENTER", 0, 0)

The big advantage of the SetUserPlaced call if the frame is supported, then you can clear/move protected frames even in combat.

There is also a similar hack with secure frames, where you can resize them in combat while StartSizing is active.
