"evolution-calendar-factory" causes flicker in the panel-calendar

System: Ubuntu 13.10 beta (3.11.0-8-generic)

When I open the calendar in the panel and point into the calendar itself, then the calendar is not constantly displayed right, but has short flickers.

My solution is to kill the process "evolution-calendar-factory". Then the flicker is gone.

Still I have no trouble with this solution, but this maybe because I have no data in the calendar.
