Changes to CGLayerRef in Ventura?

My app uses CGLayerRef to do some of its drawing. With Ventura, this doesn't work reliably. I'm wondering if there have been changes to CGLayerRef that might account for this new undesired behavior? I did not see anything in the release notes regarding it.

To be more specific, sometimes some of the drawing I do does not seem to make it to the layer. So when the layer is later drawn it appears that some of my window content is missing.

I would replicate this in a sample app if I could, but it is not possible.
