Aforementioned properties change only when mode changes, so it's enough to be set only once per mode set. Currently it's done whenever properties of primary plane are changed. 2. It's assumed that primary plane will always cover whole screen. While this is true most of the time, it's not always. DE2/3 planes are universal and mostly equal in functionality. There is no reason to add artificial limitation to primary planes. 3. The current code only works for UI layers, but some mixers do not have any UI layers.
