WordPress Twenty Seventeen Front Page Images Not Showing

I manage a website for someone, using the WordPress Twenty Seventeen theme.  I hadn’t been paying much attention the website until I just added some new content.  I also updated it to use SSL because Google is apparently going to start showing warnings on sites that don’t use SSL.

Anyway, everything seemed to be working great until I tried to view the site when logged out.  The first image loaded fine on the home page, but all of the other images below it didn’t load – it just showed a grey gradient where the images should have been.

Interestingly, the images load just fine in Microsoft Edge and Firefox.  It was only Chrome when logged out that I had the problem.

Fortunately, Google was my friend for finding a solution (for a problem they seem to have caused – as it was an update to the Chrome browser that seems to be the problem).

Hopefully, they will update the theme to fix the problem, but for now, the workaround that seems to have worked for me was to add the following to the custom CSS under appearance:

.panel-image
{transform: translate3d(0,0,0);
-webkit-transform: translate3d(0,0,0);}
