Collisions In Game View Not Working

Hey folks,

I just installed 1.9 and wanted to build a very simple test scene.
Lo and behold, it seems like collisions are broken? At least in GameView.

Looking at the debug view for Physics Colliders, the collisions are correct.
I have attached a quick gif demonstrating what I mean.

It could also very well be, that I didn’t understand something correctly. But it definitely seems… wrong.
