Just for the record. I investigated this bug a bit when I hit it some weeks ago (it wasn't with Leap, but with Qt 5.5 in SLED12) and found out it seemed to be a problem related to QtQuick/QML using openGL in a virtual machine. I've looked at the Qt changes and I can't find a reason for it to be fixed, but indeed, I installed Leap on a vm and plasma (which uses QtQuick) shows fonts correctly. So I agree this issue can be marked as resolved/fixed, but I'm not sure why and Iwill try to do some more tests with SLED12, where it was completely reproducible.
