Comment 1 David Jarvie 2016-04-12 21:47:11 UTC 
I can't reproduce this running under KDE frameworks 5,17.0.

What version of KDE frameworks are you using? (Help -> About KAlarm -> Version will tell you the KDE frameworks version.)
Comment 2 kdebugs.anon134 2016-04-13 13:03:02 UTC 
Using:
KDE Frameworks 5.20.0
Qt 5.5.1 (built against 5.5.1)
The xcb windowing system
Comment 3 David Jarvie 2016-04-13 21:16:11 UTC 
This is probably fixed for KDE Applications version 16.04 by commit
http://commits.kde.org/kdepim/37373504360a50f94ed73049ddbdfe95f5e04a82

If it happens again after updating to 16.04, please reopen.
