Bug Unity scene window/view isn't 'straight'

Hi there!
I haven't seen anybody else on Google who has experienced this, so I am reporting this here. As you can see in the picture below, the scene isn't straight in any way (on the camera relative z axis). If I'm doing something wrong, please point it out, but I would appreciate that.
And no, the world isn't somehow rotated, it is the whole scene, and the grid.
