Hi,

Are you using the latest L4.1.15_2.0.0  bsp image? I could not reproduce this issue on this version.

Now there are two ways in which you can do this,

1. Run a wayland compositor (weston) before running your Qt Application.
2. Compile qml-compositor and run it before running your Qt Application.

In both cases you have to have a compositor running if you want your application to run as a wayland client.

If you just want to run your application in fullscreen and nothing else, you can also use eglfs platform plugin and not use wayland altogether.

Hope this helps
