[UMG] Weird Focus with Touch

I start a new project and show a Widget with a Button and Combobox.
The button events are linked as such:

This is what happens if it is pressed with touch:

Events are called twice when used with touch.
When you click a combobox it opens AND closes the itemlist making it unusable.

The interesting part is, if you press the button, drag off the button and release, the click event is not called (as it should) and the combobox can be opened.

It seems to me that there is a problem with the focus when using touch. Any ideas?

Unreal version: 4.14.3

Bump.

I am having the same issue

Bump again. Same here. Very weird behaviour…

Bump again

I have the same issue: Touch input fires click event twice on Windows 10 - UI - Unreal Engine Forums
Don’t know what causes it or when it will be fixed
