Hi,
We use Vaadin Grid in our application. The scrollbar in the grid works just fine in normal resolution monitor. The scrollbar turns into a very thin line when viewing in high DPI 4K laptop monitor. The bar is very thin and it is almost a invisible line. Clicking on that to scroll is very difficult.
Has anyone faced this issue. It can reproduce it with vaadin sampler grid http://demo.vaadin.com/sampler/#ui/grids-and-trees/grid/rest-api
