Have to click Game window to play game

After moving our project to 4.13, the game window (play in editor - or packaged game) appears as normal but no focus. You have to click the game window in order to get focus and play the game.

I have tried both the normal build and the github branch.

Aside from this another problem has occurred which may be related to this. Our menu widgets all have boxes around them when navigating, even though render force rule is set to always off in the settings.

To be sure this is not related to my project, I also tried creating a new project using vR template and this has the same problem.

My Specs and setup :

Windows 10
i7 skylake 6700k
Nvidia GTX 1080
16gB Mem
Oculus Rift and software
4 K monitor (using display port)

This is very urgent as we have spent the last 2 weeks working on a huge update, and have just noticed this on our testing phase.

Dear,
Use for the first issue use the following nodes
-SetFocusToViewport
-SetInputToGame
-SetInputToUiOnly
Use these on Begin play.
Best of luck

Thanks Ali, that helps with getting the window focused on all the missions. Still left with box around the widget buttons in all menus.

Dear, I think the issue might be with the DrawAs drop down in the UMG editor.
try changing the properties there
like -Draw as Image or Button
