UMG/Slate - Breaking Change - Introducing a DPI scaling mechanism to both UMG and native slate widgets. The container widget of the game's viewport is now a DPI scaler that is controlled through a curve in the rendering settings for your project. By default the curve assumes a DPI scale of 1 at 1080, and is a linear scale up or down from that point. The math is performed based on the short side of the viewport.

Browse Source 
If you are currentlying performing your own DPI Scaling of slate you'll need to remove that code or adjust the DPI Curve of this new system to 1 and keep your current system for scaling the UI.
