The InfoTip font size in 'VA Find References Results' window is very small on a HiDPI screen with 200% scaling. It seems that the font size is not scaled properly to current DPI.
Just create a Windows 8 VM and set the scaling factor to 200%. Everything is quite large now but you get an idea how the icons and margins look on a HiDPI screen.
That is exactly what I have done, but since my monitors are only so big its a bit tricky to work in for long. There is just not much screen space left over to actually work in.
