[Interest] Widget cross-platform (minimum) size constraint problem.

[Joseph Crowell]

Your issue is that while your size code might be the same between 
platforms, fonts and therefore font sizes are not. The fonts are usually 
larger on linux. This of course results in the necessity for a larger 
minimum value for your window size. The most obvious fix is to set the 
minimum window size to the size for linux and not Windows.
