UI fonts are rendered too big

XMLWordPrintable

    • Windows

      On my Windows 11 22H2 machine with 125% system scaling the UI of Qt Creator uses fonts which are rendered too big.

      This was not happening with Qt 6.4.0

      Workaround: I've compiled Qt 6.4.1 with the fix form Qt 6.4.2 and attached the qwindows.dll binary to this bugreport. Just replace the installed version from c:\Qt\qtcreator-9.0.0\bin\plugins\platforms\qwindows.dll and this problem goes away!

      Second workaround: Another solution is to use a fonts.css and start Qt Creator as: qtcreator -stylesheet fonts.css
      The following fonts.css made the UI font size normal again:

      QWidget
{
    font: 9pt;
}

      Third workaround: Before the QApplication is instantiated this could be called.

          QApplication::setDesktopSettingsAware(false);

      However, then we might have other issues, related to themeing, which would need to be tackled. Perhaps not worth it for a single patch version of Qt which certainly won't be much used on Windows.
