Research direction

Start by reproducing ZoomIt MP4 recording with Ctrl+5 on the reported PowerToys 0.99.1 environment, then inspect the attached PowerToysReport ZIP for relevant diagnostic details. Done means repeated Ctrl+5 recording creates a usable MP4 without the transient orange frame, crash, or failure to respond.
