Cached Preview needs 2 or more frames to playback. AE Beta 22.4.0 (Build 10)

I continuously get "Cached Preview needs 2 or more frames to playback in AE Beta 22.4.0 (Build 10)" when I add a new layer or adjust a layer in my setup.
 
Simple 3D camera setup with a slow camera push in z-space. 5 layers in total, no effects. Continuous rasterization thru to a live text layer with no effects. Background/base layer is built off a quicktime MPEG-4 movie - 2.3 MB.
 
If I restart AE beta, it works fine for a little while until it pops up again. Roughly 80% CPU idle.

  Model Name: MacBook Pro

  Chip: Apple M1 Max
  Total Number of Cores: 10 (8 performance and 2 efficiency)

Hey John,

 

Sorry for the delay. Here's the screen recording: https://youtu.be/mLnzFtmOqmk

 

I'm using the latest beta version of AE (22.5.0 Build 25). I've tried booting up AE Beta in Rosetta and M1 Native, which gave the same error results. If I boot up AE 2022 (22.4.0 Build 56) as normal or Rosetta, I don't get the ram issue.

 

From looking at the Frame Render Snail in AE 22.4 it's 27ms to render the psd layer rotating but AE 22.5 Beta it's 326ms. The comp build is using a layered psd, which I'm using one of the many layers in a new comp and have a simple rotation expression (time * 50). That specific psd layer is 3029x2960 inside a 1080x1920 comp at 30fps.

 

Let me know if you need any additional information.

Hi @Seth NC,

Thank you for reporting this performance issue, and also for your patience with our response. Are you still experiencing it in the latest Beta builds? The latest Beta is version 22.5.0.1. If so, a screen recording would be greatly appreciated.

 

Thanks again for reporting, and for any further information you can provide,

- John, After Effects Engineering Team
