    Description

      The rendering for fonts appears to have changed somewhere between 6.5.3 and 6.6.3, both for "native" Quick Items like the Label and the QQuickPaintedItem.

      I have not found a workaround that comes close to the quality of 6.5.3.

      On higher resolutions it appears to be ok(f.e. 4k @ 150%), for the example below I had my screens at 1920x1080 with 100% scale.

      The used font is Montserrat.

      Qt 6.5.3 - Left QML Label - Right QQuickPaintedItem

      Qt 6.6.3 - Left QML Label - Right QQuickPaintedItem

      The shown example is attached: FontRenderingExample.zip
