An image of the Kalendar application window after resize.

SUMMARY
After resizing Kalendar application window (see screenshot), I am unable to open any dialogs, menus, or change the view. Clicking on the X at the top right of the application window generates a "Not Responding" warning notification as Kalendar freezes. 

I was attempting to resize Kalendar so that I could view my task list in a small window with as few other interface elements visible as possible.


STEPS TO REPRODUCE
1. Resize Kalendar window as shown in screenshot
2. Click between views a few times

OBSERVED RESULT
Kalendar does not respond to attempts to open dialog windows or change views. The window cannot be resized.

EXPECTED RESULT
Kalendar remains responsive.
