Physics change when Game view and Scene both visible in editor

We're running into a strange issue, ( 2019.3.6f1 ) where our 2d collisions will pass through or miss one another when the game view is the only view active. When docking game and scene together, our collisions run normally. If we close the scene view again, the same issues come back.

Any ideas? Thank you.

EDIT: Turns out my whip wasn't on FixedUpdate, which I previously thought we had changed it to.

 

Posted a video of the result, still facing this issue. @14 seconds shows the switch to Scene view.

 

Not sure if you ever figured out why this happens, but I'm having a similar issue where my player seems to have more friction or something when I have both views open. With just the game view, it slides across the ground easily. It's very strange that having the different views open can affect physics.

 

Either drag is always multiplied by the number of open viewports or you might be doing something in your code that is framerate dependent that shouldn’t be.

Are you calculating drag in Update()?
