EGLFS: QML superscrits not working (but working on X11)

  • The following code is meant to show the formula e=mc squared, with a bold "e" and "2" as exponent:

    Text {
                textFormat: Text.RichText
                text: "<b>e</b>=mc<sup>2</sup>"

    When run on PC virtual machine (Debian 10, Qt 5.11, X11) it works as expected.
    When run on embedded ( Debian 10, Qt 5.11, EGLFS) the "e" is in bold as expected, but the "2" is normal text size and position, like the <sup> and </sup> tags were missing.

    Any hint?
