Images not showing up at first. After page refresh they appear

I have the same issue too. The slideshow doesn't show unless the page is refreshed.
The slideshows are directly in a content type.

Issue is fixed & pushed to the 2.0.x branch, Will be released on the next release.

Released this issue in latest version 2.0.5 →

the problem is still present.

@antonio.cangemi can you double check, slideshow is working as expected.

Hello everybody,
I just tested version 2.0.5.
This works better, but there are still problems.
I have a site with several hundred galleries, and a software that allows you to view all the galleries, one by one.
Randomly, some galleries are not displayed, although 5 minutes before, they were displayed.
To test: https://lorraine-photographies.fr/concerts-tous.
At this moment, https://lorraine-photographies.fr/concert/patrick-bruel-nancy-open-air-2019 is ok on Firefox, Chrome, and out on Edge...
If someone wants to test all the URLs https://lorraine-photographies.fr/concert/*, they are in the sitemap.xml.
Thanks by advance,
JC

If you use an image style and the image is generated for the first time, the slider does not display the image.
