Unfortunately, the toolbar icons aren't the only problem with HiDPI 
screens on Windows (see attached screen capture). The icons of widgets 
are very small too, e.g. the outliner icons. The tabs look a bit small, 
too. Also for some reason the table-insert icon size does not increase 
when setting larger sized icons. It's not a big problem working with LyX 
that way but I think some fix would be nice.
