Video: multiple questions

Hello zingolo,

First of all, please try to disable all the active plugins, leave just Visual Composer, clear all your caches, purge CDN files if you are using the CDN system and install only the plugins that come bundled with our theme and rule out the conflicting plugins.
This theme behaviour regarding on hover on mobile it seems to come from your untested plugins which interact with the theme and which might cause a lot of unknown issues. Also, the problem which you have mentioned regarding on zoom in might come by some ads which are not correctly set (if you are not using the AdSense code and if you are using other ads and these are not added with div method might appear some behaviour like this) -> for more information about this method you should consult this -> https://forum.tagdiv.com/using-other-ads-non-adsense-ads/
Regarding on your Big Grid, please try to regenerate the thumbnails. -> http://screencast.com/t/d3jOHMWvHA For more information about this process, please refer to this topic here -> https://forum.tagdiv.com/topic/block-images/
Also, for more information about low resolution for images in mobile mode, please check this topic here -> https://forum.tagdiv.com/topic/feature-image-on-mobile-is-low-resolution/

Hope this helps!

Thanks for your understanding!
