In Unreal 4.13.2, using Chrome/Firefox, when launching any game, mouse input is not recognized when clicking anywhere on the game’s screen. unless I resize the browser to a smaller size, forcing it to full rescale the content.
After rescaling, I can get the UI buttons to be clickable again. On current APP, we have highlight when mouse cursor is over an UI element and until resize, the UI elements never register.
This was working fine on 4.12 - is there something that has changed with 4.13 that requires setting the mouse input on start differently?

Check out a new WebAssembly + WebGL 2 demo of UE4 at
That demo incorporates a number of the upcoming fixes, and mouse and resizing should work properly.
