It's started recently, I drive Acura RDX 2024, its screen is split into 2 parts, the main screen part and the additional information part. The CarPlay has a button that allows to toggle the CarPlay to be shown only on the main part, or full screen on both parts.
After the tapping the toggle button the CarPlay display size changes and the map disappears and not re-rendering again until switched to another app and then back to Waze.
