Hi, i face the exact same issue. Did you manage to understand the problem or find a solution ?

Unfortunately when i try to make picture with command line zbarcam --prescale=300x200 the result is an unreadable striped picture (see attached file). However when i use another tool like Raspistill my camera is perfectly wokring. Can you please help me with my issue ?
