Problems with high DPI settings and paper2d

This appears to be a regression as the issue does not occur in 4.17. 

When setting the windows scaling to anything greater than 100% the tile map selector from Paper2D is off. Clicking on the tile set will result in selecting a different tile that is further up and to the left of the initial click point.

1. Right click the desktop and select display settings.
2. From the display tab adjust the slider that handles the size of text,apps, and other items to anything over 100% ( I tested with 125%)
3. Create a new UE4 project and create a Paper2D tile set from any texture.
4. Open up the created tile set and make sure it is on the monitor that has the adjusted scaling.
5.  Click anywhere on the tile map and notice that it will not select the tile you clicked on but rather one that is far up and to the left
