      Description

      When running a slightly complex example app like the "Coffee Machine" example, the qmlscene puts one CPU core under load, even if the application is not visually animating anything.

      I noticed that because the cooling becomes louder.

      This does not happen with applications straight from the wizard. So, some specific Quick item might be causing that (reminds me of QTBUG-50161 ).

      Edit: This happens for me with the Qt5-based and Qt6-based kits in QDS.
      My Graphics drivers:

      Dynamic GL LibGL Vendor: Intel
      Renderer: Intel(R) UHD Graphics 630
      Version: 4.6.0 - Build 27.20.100.9664

      Edit 2: The cause seems to be the Multilanguage Database feature.
