Keyboard input is not registered in the game view. It's only registered in the scene view. The attached project uses the new input system. I tried other projects with the new input system on Ubuntu and I have the same issue.

Steps to reproduce.
- Open the attached project in 2020.1.0a14 using Ubuntu 16.04
- Open the scene BubbleBobble_lvl_1
- Press play
- Use W, A, S, D to move the character, space to spawn bubble.
Notice issue >> The buttons will only work in the scene view and not in the game view.
