I can't reproduce this with Qt 5.12.1 and konsole version 18.12.1.

Does setting or clearing QT_WAYLAND_FORCE_DPI do any difference for you (try setting it to 96 or physical)?

Comment 4 Johan Klokkhammer Helsing 2019-02-06 11:22:47 UTC 
Weird.

Can you try running the following in qmlscene?

import QtQuick 2.6
Column {
    TextEdit {
        id: size
        text: "32"
    }
    Text {
        font.pixelSize: size.text
        text: "Smileys Symbols ㋡ ㋛ ☺ ☹ ☻ 〠 シ ッ ツ ヅ Ü 〲 〴 ϡ ﭢ ت ⍡ ⍢ ⍣ ⍤ ⍥ ⍨ ⍩ ὃ ὕ ὣ Ѷ Ӫ ӫ "
    }
    Text {
        font.pointSize: size.text
        text: "Smileys Symbols ㋡ ㋛ ☺ ☹ ☻ 〠 シ ッ ツ ヅ Ü 〲 〴 ϡ ﭢ ت ⍡ ⍢ ⍣ ⍤ ⍥ ⍨ ⍩ ὃ ὕ ὣ Ѷ Ӫ ӫ "
    }
}

Comment 6 Johan Klokkhammer Helsing 2019-02-06 11:38:43 UTC 
So likely either a Qt bug and/or something weird with your fontconfig...

It works on X?

Could you file a bug at bugreports.qt.io?
