Hi, I'm opening a thread here because I ran into a curious fact using calibre's Viewer. In the page layout settings you can set the max screen area used to show the text. Along with the description for the option, calibre helpfully tells you the current width and height of the Viewer window.

What I noticed is that these values seemed too little to me, and I realized that the cause was my display scaling factor of 1.25, that I use for my 15.6 1080p laptop. With the Viewer window maximized, the values shown are 1536 and 794, which are exactly 1.25 less than the real value (minus taskbar and titlebar for the height I believe).

So I guess the question is: is this intended? And could this be misleading for non-technical users? This is really a minor problem and I know that HiDPI brings along lots of problems in implementation, but I wanted to report it in case there is an easy solution.
