[agl-discussions] ivi-shell layer visibility problem

[Ucan, Emre (ADITG/ESB)]

Hello Jan,

I think they are window manager bugs.

Surface 1 is the home screen, and surface 2 is the music player.

In good startup, visibility of surface 1 is set to 1. Therefore, it is visible.
In bad startup, visibility of surface 1 is 0. Therefore, it is not visible. Window manager has to set the visibility.

When you clicked music player button, window manager set visibility of surface 2 to 1. Therefore, music player is visible.
But window manager does not set back to 0 when you clicked the homescreen button.

Best regards
