Can you fix cordova's canvas problem for older Android versions?

There is a problem with canvas when cordova creates .apk from js/html/css. Apparently it is a problem only with older Android versions and newer versions with better processors are fine. Please, write TIP in your response, so I know you have read this job description. Also, I would like you to tell what you think is the problem and what would you do to fix the problem. Please, no beginners and guess work, just guys that do understand the problem. John
