This is an intermittent issue and affects AE, PPro and rendering through AME. This may be related to cache issues and/or insufficient memory somewhere in the pipeline.
Importantly, rendering from AME prevents the isssue about 90% to 95% of the time. But when AME fails, it's a lot finicky trying to fix the issue. Changing property vals seems to give it a required kick to get back to expected results but even this is a trial and error routine.
Has anyone else experienced this? Any ideas how to fix/workaround this?
