I use a wp theme that has a "magazine style" layout in the home page. When posting a youtube video, the video it is not resized to fit the available space, overlapping other content areas.
This only happens using both Autoptimize and WP Super Cache together. Using either alone is fine. You can see the issue here:
I don't know if it's an autoptimize or wpsupercache issue, or a theme issue. I just deactivated Autoptimize to get along.
WP Super Cache 1.2
