RenderPassManager scaling bug

Ok here is the situation, we have placed the GameTSCtrl inside a container

%guiContent = new GuiControl(PlayGui) {
...
   new GameTSCtrl(PlayGuiCtrl) {
...
  }
}

This allows us to re scale the render window, which works for the most part.

However if glow or transparency is in the scene we get a weird rendering side effect. When the GameTSCtrl is scaled it looks like there is a scaled down rectangle within the GameTSCtrl. Within that rectangle everything renders properly. If I go into the GUI editor and rescale the GameTSCtrl the interior rectangle also scales. It looks like the glow/translucent/shadow buffers scaling is off. Note this only occurs around glowy things, and is most prominent when the sun is below horizon.


Any ideas?
