The ColorPicker Dropper tool next to Color fields on components (not inside color picker window) are not working as expected if Windows app & font size is set above 100%. This is often the case on systems with hi-res displays (4K, laptops etc)

In some cases the picked area is offset or the window looses focus.
(Tested on Windows 7, Windows 10)

Repro steps:

1. On Windows 10, right click desktop and select 'Display Settings'
2. Change the slider that increases font&app size to above 100%
3. Open Unity
4. Create a new Light or Material
5. Click Color picker dropper icon next to a color field
6. Observe incorrect color is picked at pointer
