Hello Martin,

Into your picture I saw 2 things like a colored background with 2 colors

1 & 2 have not same color and we can see the "line" between

And you texte is just on this "line" too

Mays be is it the source of your issue

Enjoy!

Dobrý den, ta "čára" se nezobrazuje jen v textu a stále na stejném místě. Někdy se tam zobrazí i 2x pod sebou. Tuto chybu pozoruji jen u stránky která je delší.

Does it a colored background or picture ?

Try to remove the background, to change color,...etc

Probabaly the issue is into this way.

Or give us your page web link to see from our side.

Enjoy!

The objects (text-object, image-object and menu-object) has maybe a setting for the background. Normally the background for an object is default set to transparent - have you changed that?

Hello Martin,

Here my video capture of your page.

It's strange because the green color is "raining" into the background, and when it is finished, some errors appear

Many errors seem to be from an youtube iframe api and widgetapi.....

And other errors from the embedded play used by youtune, I beleive.

So it is probably not an issue with WSX5, but more a bad code/script intregration into your page.

Please check twice your cod eintegration into this page

Just for a quick check... disable or remove your youtube video to see if not the source of your issues !!!
And afterr investigates step by step.

Hope this helps

Enjoy!
Axel

Ze stránky jsem odstranil video z youtube ale popisovaná chyba se zobrazuje stále
