Comment (by gk):

 Some Windows experiences with the latest round of patches:

 If I set the DPI to 150%

 1) the height/availHeight is always off by one on start-up.
 2) the height/availHeight is always off by one if I resize manually +
 maximize the window + shrinking the window with the button next to the
 "x".
 3) making the window fullscreen loses around a third of the available
 space. I wonder if there would be something better we could do here as it
 seems that there is enough screen height available to get the fullscreen a
 bit more fullscreen-like (see attached screenshot)

 If I set the DPI to 125% then I only get the off-by-one problem very
 seldom after resizing manually but I can't reproduce it reliably.

 Another thing I found confusing was that while resizing the width (just
 dragging the window) my height gets adjusted as well. There seems to be
 only a particular step when this is happening (if I am dragging the window
 and my mouse cursor is between approx. 75% and 90% of my screen width).
 Oh, and this is only happening if the window has max height. This only
 happens if I touch the DPI settings it seems.
