Why SetInputModeGame duplicate touch event !?

Hello,

I actually work on mobile game. But I’ve an issue when I use SetInputModeGameAndUi (or GameOnly).

My test on actor:

Before press Q, that work fine.

After press Q, most Moved events are duplicated:

“Use Mouse for touch” is on

Any idea what can cause this?


Update:

Tested on new empty project, with an empty actor and just the script above (and EnableInput on Event BeginPlay).

Only “Use mouse for Touch” enabled on project settings.

Duplicated events on same frame still there, after SetInputMode.

That look like an engine bug ?
