Blender's EEVEE Rendering with Compositor

When rendering animations using the EEVEE engine with the Compositor enabled, the final render sometimes shows inconsistent results. Occasionally, frames appear without the composited effects, and sometimes there’s a brief flash of the uncomposited image before the composited result is displayed. This inconsistency makes it hard to verify if there are any compositing issues in the final output.

Ideally, the final rendered frame should only display once both rendering and compositing are complete, so users can view the finalized result without confusion.
