The error occurs when running with -platform cocoa:fontengine=freetype on macOS 15.

Running with -platform cocoa:fontengine=freetype

import QtQuick

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")
    Text {
        anchors.horizontalCenter: parent.horizontalCenter
        text: "测试"
        font.pixelSize: 9
        font.weight: 400
        font.family: "PingFang SC"
    }
}

It worked fine on macOS 14, but after upgrading to macOS 15, errors started occurring. After my quick check, I found that the error does not occur when font.family is not specified, but it does occur when specifying font.family: "PingFang SC" (Note: PingFang SC is a native Chinese font included with macOS,specifying other fonts like Helvetica results in the same issue).This ultimately leads to font rendering errors in the application’s interface.

After further testing, an error occurs when rendering Chinese font content.that even without using FreeType fonts, although the console does not report any errors, the rendering results are still abnormal and differ from the rendering on macOS 14.
