Also, if you're using the SecureStateDriver system, they don't necessarily listen to these events and are delayed by at least 200ms. You might be able to hook into the OnAttributeChanged script to act on when RegisterUnitWatch() triggers. If you leave it to show/hide the frame itself, it changes the statehidden attribute to a true/nil value.
At this point, I'm just running off a list of what could be going on. I don't see what self:UpdateDisplay() is doing or how unit switching is being handled not only from the artwork aspect, but how the SecureUnitButton template is being used. All that's being shown is debug code that isn't really going to work in the end product.

My secure state looks like this:
Lua Code:
self.frame.state = CreateFrame("Frame", nil, nil, "SecureHandlerStateTemplate")
self.frame.state:SetFrameRef("ZPerlPlayerPet", self.frame)
self.frame.state:SetAttribute("_onstate-vehicleupdate", [[
--print(newstate)
if newstate == "invehicle" then
self:GetFrameRef("ZPerlPlayerPet"):SetAttribute("unit", "player")
else
self:GetFrameRef("ZPerlPlayerPet"):SetAttribute("unit", "pet")
end
]])
RegisterStateDriver(self.frame.state, "vehicleupdate", "[vehicleui] invehicle; none")
By default i only use the *ED events but thats when the issue happens, thats why i added the *ING events to hide the frame between them.
The UpdateDisplay() funtion is noting special just updates the frame, name level buffs etc. Also my SecureUnitButton has nothing special it's using the RegisterUnitWatch method.
