Apparently both are related to this upstream bug: https://bugreports.qt.io/browse/QTBUG-42985 Leap 42.1 KDE is basically unusable in this state and, as far as I can tell, upstream provided a bugfix but decided not to implement it in QT 5.5. Would it be possible to upgrade QT in Leap to 5.6? -- You are receiving this mail because: You are on the CC list for the bug.
