[Graph Gallery]Components inside the example are overlapping

Components inside the example are overlapping and text inside the buttons is getting cropped

Steps to Reproduce:

1. Open Graph Gallery example
2. Build and run it

Actual Result:

1. Graph is overlapping the control panel on the right
2. Text inside buttons is getting cropped
3. Text labels are getting cropped

Expected Result:

All components should be displayed without any overlapping

Reproducibility: 100%

Note: 

Application window size seems to be the issue, if I make the application fullscreen then it is resolved. 

Two screenshots are attached with this, one is of the actual size of application and other is when fullscreen mode is selected.
