we have a problem with an animation of coloured “Image-Cards”, which turn around on click to display a word (text). It’s for learning languages.
Everything works fine, but we have unexplainable lines in the images, before the animation starts. It depends on scaling, if you can see them. A fine, white line in the middle, like dividing the image, over the whole page. Small black “rests of lines” in the middle, too. Can’t explain it better…maybe anyone here has had similar “effects”…?
We have tries so much now with fading in & out, setting visible/invisible keyframes and so on. Nothing worked. It appears in every Browser and in most mobile devices, depending on resolution/screens…
Any idea? It’s really urgent…
Thank you very much!
