According to this after the first cycle the frame's width must have
increased from 1500 to 1536 pixels.  Can't you confirm that visually?

What are the pixel dimensions of your screen?  Maybe 3142 is already at
the right edge of your screen and the window manager refuses to increase
your frame any further.
