UIToolkit problem, ScrollView not registering any inputs in Game window

Problem with Unity 6.3(LTS)

I’m trying to learn UIToolkit and testing the ScrollView component. However I quickly ran into a bug(?)

No matter what I try, the ScrollView is unresponsive in the Game window.
It works correctly in the Simultor window. It works correctly when I create a Build. Yet no luck with the regular Game window - no inputs register. Not clicking/dragging any of the controls or using the mouse scroll wheel.

Am I missing something?

OK, I found the solution, posting this in case someone runs into this:

  1. Go into Input Debugger (Window->Analysis->Input Debugger)

  2. Under “Devices” make sure you have any sort of Touch devices removed.

Apparently having touch input enabled here causes all sorts of problems when testing.

This thread got me on the right track:

PS. I also created an InputConfiguration asset from Edit->ProjectSettings->InputSystemPackage->Settings (didn’t change any settings, just created it with default parameters), this probably doesn’t influence anything but mentioning it just in case.
