OK, when it comes to the GameTooltip, it's maybe different.
But I found a solution for your problem some time ago and posted it on the Blizzard forum:

Lua Code:
hooksecurefunc("GameTooltip_SetDefaultAnchor", function(tooltip) tooltip:SetPoint("BOTTOMRIGHT", UIParent, "BOTTOMRIGHT", -500, 500) end)
