WP 4.2.3 Update Breaks twenty-twenty

Hello,
I just upgrade to WP 4.2.3, in my enfold theme, Safari browser. I have about a hundred before/after images which I use in my photography blog article. Each one of those articles is broken.

Only one side of the image displays. as an example ;

If you could advise when update is avail or a fix (CSS ?) I would appreciate it. I may have to fallback my WP if I can get a fix ….

thanks for your help
