Width and height warnings when configuring full screen

myguysi

I'm developing my first app with PySide6/QML running on a Raspberry Pi 4 and I'm having an issue when configuring it to run in full screen. I'm seeing the following warnings printed out multiple times in the console when the application starts and again after button interactions.

qt.qpa.wayland: Configure event with maximized or fullscreen state contains invalid width: 0
qt.qpa.wayland: Configure event with maximized or fullscreen state contains invalid height: 0

It's more of an annoyance than anything adding noise while I'm trying to debug printing to the console but I've yet to find a solution and would appreciate any suggestions. Here's the code:

ApplicationWindow {
  id: root
  width: 700
  height: 400
  visible: true
  visibility: Window.FullScreen
  ...
}

qt.qpa.wayland

Unless somebody else knows better, I would say it's a Wayland issue.
Wayland doesn't let you update and move the window as you wish.

Please try this example. If it causes the same qpa errors, you can file a bug.

I encountered the same problem using pyqt6 on Raspberry Pi 4b.
