        self.options['qt'].with_zstd = False

When I build and run a simple QML application with text:

import QtQuick
import QtQuick.Controls
import QtQuick.Layouts

ApplicationWindow {
    visible: true
    title: qsTr("Hello")

    Column {
      Label {
        text: "Hello world!"
        font.pixelSize: 52
      }
  }
}

It does not render the text at all. There is no error printed either (can I make QML more verbose?). ldd does not show it is linked with fontconfig.

When I build against the pre-compiled GCC 64-bit binary (using aqt), the above works. ldd shows that the executable is linked to fontconfig and libfreetype.

ping @bverhagen, Can you please retry with option qt:harfbuzz=True ?

[bverhagen]

@ericLemanissier : Apologies for the delay, testing with that option enabled slipped my mind.

I retried with harfbuzz enabled and that indeed fixes the issue! Thx!
