When using Fullscreen Mode in OSX without the native resolution then the mouse position in UMG is calculated wrong. I see the Cursor on the screen but the Widgets responds at a different position (left over the cursor). It seems that the Position is calculated by the OSX Resolution.

UE 4.8.2 Launcher Version

Hello user37337,

I have a few questions that will help narrow down what issue it is that you are experiencing.

Quick questions:

1. Can you reproduce this issue in a clean project?
2. If so, could you provide a detailed set of steps to reproduce this issue on our end?
3. Can you provide screen shots of the blueprints involved?
4. Does this issue occur when using the “Get Mouse Position Scaled by DPI”?

Yes I was able to reproduce it. Start this on a Mac from Editor as Standalone Game and try to click the button.link text
