You can try downloading the latest version of Backstretch (the jquery plugin that controls the background image scaling) and see if there's a fix for that (although I don't see that mentioned any where in the changelog):
https://github.com/srobbin/jquery-backstretch...

Just override the file at packages/theme_clearview/themes/clearview/js/jquery.backstretch.min.js with the new one.

Then make sure you clear your site's cache (Dashboard->System & Settings->Clear Cache) and browser cache afterwards.

thanks i will try to do that today. another question can u make menu to be
open by default on mobile and tablet devices? Otherwise menu button is so
small and dificult to access.
thanks

See this thread about how to make it open by default:

Note: this will be open on any browser/device. There's really not an *easy* way to make it only for certain devices. You would have to do a browser/device check in order to do that.

Unfortunately did not work :(

Bummer. You might want to search here and see if anyone else has submitted it as an issue and if there's any fix. Or you could submit it as an issue:
