Description

Attempting to use the Editor with a 32:9 Ultrawide monitor (5120x1440) causes the ratio sizes to be multiplied by 868.000000.

Steps to Reproduce
  1. Launch the UE4 Editor on a linux machine with a 32:9 ultrawide screen (5120x1440).

Results: The log prints - SDL_CreateWindow in LinuxWindow.cpp fails: "Unable to create a Vulkan window - make sure an up-to-date libvulkan.so.1 is installed."

A bit of searching reveals sdl error: "window is too large" values for ClientWidth and ClientHeight: 954810, 642354

Expected: The UE4 Editor launches normally
