"overflow:auto" creates this effect. If I remove that style, the scrollbar is gone but also vertical scrolling (in case the page is longer than the screen) is not working them. The horizontal scrollar that appears is actually not needed since it scrolls only one pixel and from what I can see in the page, there is no (visible) overflow.
I assume that the tweaked styles for the updated layouts have caused this effect. Can you reproduce this iussue? In my main layout, I have remove the bar at the bottom of the screen.
This CSS rule has existed for a long time so I don't think the last update caused the issue. Unfortunately we can't reproduce it locally just by removing the footer of the layout.
A quick fix should be to add this to the styles.css file.
.rz-layout .rz-body {
overflow-x: hidden;
}
Still we would like to find what is causing the issue - can you send your application to info@radzen.com? We can try reproducing the problem just with the meta directory of your app.
We released Radzen 2.80.3 which should solve this issue (as well as a few others). IDon't forget to upgrade your custom theme by going to the app settings and clicking the save button.
