second flickering image below some zoomed simple images

Below some of the zoomed images on my website, I see a flickering duplicate of the photo when zooming in or out (with mousewheel). I have tried with firefox, chromium, opera and midori (all on linux), and disabled the compression of the js code, which did not help. (minified with JSMin in a bash script)

version:

yarn list v0.28.4
└─ openseadragon@2.3.0

Maybe somebody has an idea what could cause such behaviour… Here is the javascript, used to start OpenSeadragon: Thanks for any help.

                viewer = OpenSeadragon({
                    id: 'osd',
                    prefixUrl: '/img/layout/openseadragon/',
                    tileSources: {
                        type: 'image',
                        url:  '/img/graf/f/flvr{{ $photo->id }}.jpg'
                    },
                    toolbar:'toolbardiv',
                    showZoomControl:false
                });

Wonderful, thank you for testing it, and I’m glad it fixes the issue. 😃

I can’t find the openseadragon.min.js. It does not seem to be in yarn, yet. How can I install it without yarn? Thank you very much

edit: I have installed grunt and it built openseadragon. It looks good here. I can’t see the second image below. It is also uploaded to the website.
