Hi, I am on Windows 7 and have tried Mathematica v9 and v11, both have the same issue when the system's screen text size sets to 150% (you can do so by going to 'Screen Resolution'->'Make text and other items larger or smaller'), emf exported from a graph will come with white spaces on the bottom and right hand sides, like screen shot below. Other image types (png, jpg, bmp, pdf) are exported fine though. How do I work around this? It looks like a bug in Mathematica.
