Solved Square feature images changed to rectangle

My feature images for the filterable portfolios started off as square (the images are square). At some point they turned into rectangles, and I can't figure out why. Can anyone help?

Here's a page with a filterable portfolio that shows the problem:

So close -- it makes the images square, but it is not showing the entire image. For instance, the first image in the portfolio at the link below should show the entire words 'logo design,' but it is cutting off the sides of the image.

Ideas?

 

BTW, I tried the other 'object-fit' options too, and they all distort the image in some way.

 

The 'logo design' image was probably a bad example. Take a look at the attached images. You can see that the feature image from the screen shot is stretched when compared to the file 'RtR-feature2.png.'

 

Well, that's interesting. I clear the cache, and sometimes I get squares (rather than rectangles), but then when I refresh the page it's back to rectangles again. The first image, the large S, never does change to a square, no matter whether I clear cache or not. See attached. This happens in both Chrome and Safari.

After clearing caches multiple times (sometimes the images showed as squares, sometimes as rectangles), I rebooted completely. Now it looks fine in Chrome, but in Safari images are still distorted. Is there a solution?

 

Correction: many of the portfolios don't look correct in Chrome either -- some do, some don't.

 

In Firefox, everything looks perfect. All portfolios load with square images and none of the images are distorted.

 

Neither of those works in Safari or Chrome, though they both work in Firefox. But thank you for that idea. Any others?

 

Problem solved: I deactivated JetPack, all images are square and fit accurately.
