So it only happens if all conditions are met: Font is Ubuntu and Qt falls back to Droid Sans Fallback (which is from package fonts-wqy-microhei) Pixelsize is 69 as computed from the 50GUs and Grid Unit size of 23 Font weight is Light
Random characters are not shown.
Seems a bug in Qt's font fallback logic - similar report at https://bugreports.qt.io/browse/QTBUG-32470
Can someone try on Wily?
