Fullscreen 21:9 aspect ratio offsets mouse cursor from UMG

When applying a 21:9 resolution in fullscreen, UMG buttons and mouse position will no longer match up.
This makes it very difficult to interact with UMG elements

Steps to reproduce:

  • Make simple UMG elements that lets
    you apply resolution using “Get Game
    User Setting”
  • Start game either as packaged or
    “Standalone Game” in editor.
  • On a normal 1920x1080 monitor, apply
    a 1280x540 resolution in fullscreen.
  • When in fullscreen mode, hover over
    buttons or interact with them, the
    cursor trigger area has been offset.

Other resolutions like 1280x600 works fine, but when going down step by step to 1280x580, 1280x560 and so on, the hitbox area gets more and more shifted in fullscreen mode.

It also offsets on 1280x620, x640 and x660. But 1280x680 works fine. (On a 1920x1080 monitor)

Windowed modes works fine.

Some monitors appears on the market now with 21:9 2560x1080 resolution. Trying that resolution on a 4k screen, the widget hitboxes offset way out up to the right.

I do not have an actual 21:9 monitor to test on. (I was given this bug by a marketplace customer)

I have attached a sample project with a simple UMG to change resolution.

5.3.2

Using fullscreen functionality with alt F11 or FDisplayMetrics with multiple displays is causing UMG offsets issues.

Steps to replicate:
Make a widget with a button.
Press F11 in a new pie window or packaged client
move window to another display
Press F11 again for fullscreen
Trying hovering over the button.

Possiblty something to do with the delegate call to RequestUIUpdate() from UGameUserSettings::ApplySettings
