UMG Scaling messed up by Windows display scale setting?

Having a problem where UE4 seems to be using Windows’ display scaling setting (the one labelled “Change the size of text, apps and other items” in the “customize your display” menu.) Setting that to 150% makes the UMG elements in UE4 scale up enormously and it completely breaks my menus. Is there any way at all to make UE4 ignore this setting and just scale using the game’s rendering resolution? Because that scaling works 100% fine.
