Can you say specifically which CPU you are seeing this on, and which you are not seeing this on, please? Also, please can you make sure you're testing with the latest version of AVPro Video (version 3.4.2). :)

Is this reproducible in a new project, running only the demo scenes?
Have you seen this issue on any Intel devices?
