Gui rendering in the wrong spot when window is resized

[The_Fireplace]

Ok, I have a Gui which renders fine when the window is small, but when the window is maximized/put in to fullscreen, it renders in the wrong spot.

 

 

My setup is: the UtilityGui renders, then at the end of its render code, tells the overlay gui to render on top of it. Then, the foreground(just 1 item icon in the screenshots) renders over that. The foreground and UtilityGui render correctly, it is the overlay gui(GuiFireplaceCoreTab) that is in the wrong spot. Here is my code:

GuiFireplaceCoreTab:

GuiModTab(superclass of GuiFireplaceCoreTab):

UtilityGui(link to the line it makes GuiFireplaceCoreTab render):

You should move your gui constructor code into the initGui, since it is called when gui is opened and scaled.

All that did was cause the gui to center on 0,0; at least when it is in the constructor, it centers correctly when the screen is small.
