Resolved Pan and Zoom sensitivity is so low (3D scene)

I sometimes have a problem when I try to move around the 3D scene, but it is very slow

These are the two tools:


In the first case, I usually use the middle mouse button, and in the second, I scroll the mouse wheel

Can't figure out why this happens

The sensitivity of these two tools just drops to impossibility. Sometimes the sensitivity becomes higher, sometimes lower. Sometimes sensitivity returns to normal

 

Select some GameObject in your scene (doesn't matter what) near where you're working.

Get the mouse cursor over the Scene window and press F, or else use Edit -> Frame selected

This resets the scene cam, should get everything kosher again.

Alternately try using Reset Layouts in the upper right corner, but that's more drastic.

 

I tried this option. Everything kosher again
Thank you!
