Note: this issue was originally reported to the Recorder team but can be reproduced when using only the multiframe API without the Recorder package.

Reproduction steps:

1. Open the attached [^2023.3.0a17_hdrp_accumbug.zip] project
2. Open the {{OutdoorsScene}} scene
3. Select the {{Main Camera}} GameObject
4. In the {{FrameManager}} component's context menu, select the {{Start Recording}} option

Expected result:
The Scene View and GameView windows should display the rendered content of the scene without any artifacts or unexpected behaviors

Actual result:
The Scene View and Game View windows start flickering black/white and the images recorded on disk are incorrect.

NOTES
The issue only seems to happen when specific values are used with the multiframe API. Notably:

• {{Samples}} = 2
• {{shutterInterval}} <= 0.5
• {{shutterFullyOpen}} > 0
• {{shutterBeginsClosing}} < 1

The problem might still be happening with other values but I've found this combination to be the most visible/obvious.
