No space between letters in text

Hi!

I'm facing issue with fonts after migration from 5.14 to 6.2. After fixing all compile issues and starting APP there were not a single font showing.

I tried to start a simple example application from qt creator that simply show ScrollView:

import QtQuick
import QtQuick.Controls
ApplicationWindow {
 id: root
 width: 480
 height: 272
 visible: true
 font.family: "DejaVu Serif";
 ScrollView {
     width: 480
     height: 272
     clip: true

     Label {
         text: "A\nBC\tGD"
         font.pixelSize: 24
     }
 }
 Component.onCompleted: console.log("Application font: " + root.font.family + "\n" + "Fonts available: " + Qt.fontFamilies())
}

And here is output in console:

QML debugging is enabled. Only use this in a safe environment.
QStandardPaths: XDG_RUNTIME_DIR not set, defaulting to '/var/volatile/tmp/runtime-root'
qml: Application font: DejaVu Serif
Fonts available: DejaVu Sans,DejaVu Sans Mono,DejaVu Serif,Monospace,Sans Serif,Serif

This told me that all the fonts are correct. But text on screen renders as if font.letterSpacing set to zero. If I set font.letterSpacing manually to 20 text is displayed again.

App is running on Yocto, Qt is build from meta-qt6. Qt was tested with and without fontconfig support.

Any thoughts what I'm missing?

I have had another experiment with fonts. FontsMetrics gives me next results for text with letterSpacing set:

qml: Font metrics: averageCharacterWidth: 12.84375| boundingRect("AAA"):QRectF(0, -22.0781, 51, 28.7969)

And for letterSpacing not set:

qml: Font metrics: averageCharacterWidth: 12.84375| boundingRect("AAA"):QRectF(100000, -22.0781, 0, 28.7969)
