   Another observing: any window cannot set/restore its position.

   QTBUG-80612:

   Then it works as it’s supposed to work. Apps (windows) are not allowed to position themself in Wayland. This is a Wayland limitation, not a missing feature or broken behavior.

   I’m not exactly sure there’s anything for us to fix here, and I’d assume support will improve with new versions of Qt? In any case, if this is something you’d like to keep tabs on, can you open a tracking issue on the GUI repo?
