Hi all,

I have a display device that supports up to three different display buffers: one graphic layer and two video layers. The graphic layer is at the top (zpos=2).

I'm using Weston (DRM backend) with a Qt5 application at full screen (graphic layer). Weston is using pixel format XR24 even if Qt5 is using AR24.

In another application I have a video player application that renders by DRM into a video layer (zpos=1). The problem is that the HW alpha composition is not working due to Weston pixel format and because of that I'm unable to see the video layer.

Is there any configuration option to force Weston to use AR24?

Thanks,

Santiago Otero
