When the tab bar on the comics widget is wider than the current comic, the icons and names are drawn outside the widget (see screen shot 1).
When moving the widget around, these icons often produce artifacts on the screen (see screen shot 2).

Reproducible: Always

Steps to Reproduce:
1. Add the comics widget to your desktop
2. Add a few comics
3. Select a comic which is not as wide as the tab bar with the comic names

Actual Results:  
When the tab bar is wider than the image, some icons are shown outside the box. When you can't reproduce it the first time, try changing the comic a few times without resizing the widget.

Expected Results:  
Neither icons nor names should be drawn outside the widget box. No artifacts should be left on the desktop.
