with the browser’s developer tools, I’ve discovered that when I go with mouse over a button (and same other control), this warning comes up
119391 qx.theme.manager.Appearance[22-0]: Missing appearance: button/label
What is it?
those are just debug logs, they don´t do any harm besides a (slight) Performance decrease.

You can disable logging by Setting debug to false in web.config or in Default.json
