Hoping someone can help me out with this one.  I'm embedding a video to show you what I'm trying to illustrate here.  It seems that whenever I try to capture with xvidcap the file images is only refreshed when the cursor passes over the area or when I bring up a new window.  I'm illustrating here with Blender, the same happens with Firefox in most instances.  The effect is the same no matter what codec I'm using.  I'm always capturing with --audio no flag. 

System:

Ubuntu Feisty Fawn

xvidcap 1.1.6 pre-compiled .deb package
