    Description

      The following example creates separate distance field textures for each Text element:

      import QtQuick 2.0

Item {
    width: 400
    height: 400

    Text {
        font.pixelSize: 24
        text: "My Sample Text"
    }

    Text {
        font.pixelSize: 25
        text: "My Sample Text"
    }
}

      Output is:

      qt.scenegraph.time.glyph: distancefield: 11 glyphs prepared in 1ms, rendering=0, upload=1
qt.scenegraph.time.glyph: distancefield: 11 glyphs prepared in 0ms, rendering=0, upload=0

      This appears to be due to changes to the cache key between 5.6 and 5.8 – using QRawFont directly rather than a custom QString key.
