I've attached a video exhibiting the behavior in a new comp importing a ProRes 4444 video into the 16bpc project.

Christian, we are not aware of any such behavior. This sounds like a bug of some sorts.

However this really doesn't give us any of the details we need to understand and solve your issue.
To get started debugging the issue, we need to know:
0. Which specific version of AE are you using (as shown in the "About After Effects" dialog)?
1. System Specs (Platform, OS, Hardware, GPU, Drivers, etc.).
2. AE Preferences settings (particularly Memory & Disc Cache settings).
3. Specific details about your Project and the Comp you are working with, things like —
Imported footage types (and resolution)
Project color bit depth
Comp Resolution
Number of layers
Effects applied
Expressions
Etc., etc.
4. What are the exact steps you are taking from when you launch AE to when the issue occurs?
5. What errors or other feedback are you seeing?

Let's figure this out.

Thx!
