Unity starts baking when moving the view in the scene

I downloaded the latest version (2017.2.0f3) of Unity, and opened my old project, then I got this problem. Every time I use my mouse to navigate the Scene View, Unity start to bake something (Create Geometry, Layout System, Clustering etc.). I didn’t move anything in the scene, I simply did a mouse scroll to move the Scene View forward, then Unity started baking something again. Did anyone know what the problem is?

After I downgraded my version to 2017.1.2f1, I no longer have the problem, so I can confirm that this problem is caused by the newer version of Unity. However, I haven’t found a way to reproduce this issue, my scene is a little complex.
