The camera is a 2 node camera, both Position and Point of Interest (Â the 2-nodes) need to be animated.
When the Camera crosses the Point of Interest the camera turns to face it.
The solution is to either use a one node camera which only uses position (it’s found under camera options) OR to animate the Point of Interest as well as Position.

One option to automate the process is to use the Cylinder script found here to generate single row of elements in a 3D cricle.

One method that will work is to use text arrows from a font e.g. Zapf Dingbats or Wingdings and apply the 3D Rotate Around Circle preset.

[Justin Maloney] “For example. A wiggle effect on opacity, to make an image fade in and out, that always remains at at-least 50% and wiggles from there.”
Wiggle can take several parameters, the first 2 are frequency and amplitude. Wiggle uses the current value of a property as a base, so setting opacity to 75% and the wiggle amplitude to 25 would restrict it to between 50% and 100%.
i.e. wiggle(2,25) would wiggle opacity 2 times a second with a range restricted to 25 from the base value.

[James Hernandez] “The thing is that I’m not moving the camera when I hit the 3D button. I can see the layer just fine when the camera is on it and it’s not a 3D Solid. But if I make the Solid into a 3D layer, it goes transparent.”
Focal length of the camera, zoom settings and dof, any of those can affect what the camera view displays.
Is the camera visible in the default custom views? If so is the camera facing the 3D layer? If it is check the settings for DOF and Zoom.
Here is a video demonstrating the issue if these settings are inadvertently changed:

[James Hernandez] “I simply created the camera, the null and then the solid. I never moved the camera.”
What is the focal length of the camera? What is the Zoom level? Is DOF on or off? What is its position relative to the layer?
-
I assume it’s the camera position relative to the layer. The camera is pointing away from the layer. Try resetting the camera position, orientation, rotation and point of interest to the defaults.
Since the camera is parented to a null you could reset the null’s position as well. Or just delete the camera and null and replace with a new camera.

[Marc Eijkelenboom] “Would you know of any settings maybe that could fix this?”
Not that I’m aware of. This is now part of the UI that Adobe has to take advantage of the Retina display.

This will happen on a MacBook with a Retina display since the display has twice the normal pixel density.
