self:SetRenderBounds is acting funny

[Lexic]

As opposed to doing the expected action of making my dynamic boxes always visible even when the two corners aren't, this makes my box flicker wildly, and sometimes go entirely invisible, usually when I'm looking at a corner.
However, if I can't see either corner, it [i]is[/i] visible. (usually)
Specific:
[lua]function ENT:Draw()
self.Entity:DrawModel()
local other = self:GetNWEntity"other"
if not ValidEntity(other) then return end
local pos = self:GetPos()
local pos2 = other:GetPos()
if (pos ~= self.pos1 or pos2 ~= self.pos2) then
self:SetRenderBounds(pos,pos2);
self.pos1 = pos;
self.pos2 = pos2;
end
-- ...

[QUOTE=Gbps;18398364]The reason you are getting that problem is because you are calling SetRenderBounds every frame, causing the engine to update the bounds ever draw frame, causing the flicker. When you were not looking at the corners, everything was fine because the draw hook wasn't being called, therefore you weren't updating your render bounds ever frame. Only call SetRenderBounds when the placements of the corners have changed and you should be good to go :eng101:[/QUOTE]
Nope, look again.
