UMG buttons not clickable when capturing viewport permanently

Hey Toraxxx-

The OnClicked event of a UMG button printed as expected for me with Capture Permanently Including Initial Mouse Down set. Are you able to reproduce this issue in a new project without added content? If you are able to reproduce this, can you provide a sample project for me to test directly?

I upgraded my project from 4.13 to the 4.14 Preview 2 and all buttons are not clickable anymore when the Default Viewport Mouse Capture Mode is set to Capture Permanently Including Initial Mouse Down or Capture Permanently.

OS: Windows 10

I just made an empty project, created a UMG widget with a button that prints something. The issue still exists.


The only time it works is when the window is unfocused and you click on a button. When the window is in focus the buttons arent clickable anymore (and they also don’t have mouse-over animations etc.)

Project:

Thank you for the clarification. I was able to find where this has been reported Unreal Engine Issues and Bug Tracker (UE-37698). You can track the report’s status here as the issue is reviewed by our development staff.

Cheers
