I've just built what's in AGL master now. The HomeScreen shows up and I can press a button, but it the interface only reacts on the first action (or maybe two actions if you look in the logs) and the freezes. I don't see anything suspicious in dmesg. The only log I've got is from WindowManager.service:

    Dec 12 11:03:40 porter WindowManager[714]: -=[hideLayer]=-
    Dec 12 11:03:40 porter WindowManager[714]: layer 2
    Dec 12 11:03:48 porter WindowManager[714]: -=[showLayer]=-
    Dec 12 11:03:48 porter WindowManager[714]: layer 2

at 11:03:40 I've pressed "Home" button on the upper toolbar, and the 9 buttons in the main area showed up. At 11:03:48 the "HVAC" button in the main area and nothing happened but the log message. It's pretty the same with other buttons. Wayland itself doesn't crash, you can just "systemctl restart --user HomeScreen" and press a button once more.
Anybody experiencing the same problems?
