(1280-16) means the window is 1264 pixels wide.  Not 1280 pixels 
wide at 16 pixels offset.  

> Negative values are relative to screen size. 

OWIDTH=-80 means 80% of screen width?

Appears the window is located by Left :=0; ... Bottom :=0; in the 
body of Display.  Change and recompile to shift the window.

FWIIW,
https://en.wikibooks.org/wiki/Guide_to_X11/Starting_Programs#Specifying_window_geometry
describes a convention which would make OWIDTH and OHEIGHT 
unnecessary.  The offsets can be useful with your 4K device.
