PIE window doubles every time you start the game

When setting the PIE window position under “level editor - play” in the editor settings, the position gets saved, and when starting the PIE in a pop-out window, it gets doubled (or multiplied with the windows scaling settings). This number then gets saved, effectively multiplying the position every time you start the pop-out PIE.

Here is a link to the problem in action.

It seems to only be an issue on UHD screens that use a different scaling than 100% (set in the windows settings).

I tried reporting this bug on the Unreal Engine bug submission form, but it kept loading infinitely on several different browsers and PCs, so I came here instead.

Steps to reproduce:

  1. Open an Unreal Project on a 4k screen with >100% scaling
  2. Under the Level Editor - Play settings, set the Game Viewport setting “New Window Position” to something other than 0/0
  3. Play in editor in a new window (pop-out)
  4. Close the resulting window
  5. The position set under the “New Window Position” will have doubled / changed according to the DPI scaling

Hello,
