Comment 1 for bug 1659256

confirmed on Windows 10, Inkscape 0.92+devel 15423.

in trunk:
setting the window size to large leads to the preferences values:
     id="desktop"
       width="1200"
       height="675"

setting the window size to small leads to the preferences values:
     id="desktop"
       width="1274"
       height="873"

so the "small" window is slightly larger than the "large" window
