Game window automatically resizes back to default when window focus is returned

Hi, I am making a game and the standalone test build will return to its default resolution (in this case 1280 x 720) when i return focus to the game window. So how this happens step by step is:

  1. I open the game and re-size the window
  2. Click on another window (Skype, Chrome etc) then either minimizing that window or clicking on the game window in the background will re-size the window back to whatever its default resolution is.

Here is a video I made of the issue: - YouTube

Also, doing some research on the issue, I have noticed this has been a problem for the past 2 or 3 years. I have not been able to find a solution for this and am wondering ifr its fixable in blueprint, and if so what exactly can be done to fix this, if not does it have to be fixed in C++? if so, what .cpp file has the issue.

Thank you.

I have the same issue
