On Vaadin application load

When we load the application in the browser (type in localhost:8080/appname), the screen displays a light grey background with an ugly spinner in the center is shown (not the nice new blue valo spinner). What is this, and how do I beautify or modify this screen?

Hi,

Are you setting the theme on your UI, using @Theme annotation?

In case you have a custom theme, as it happen with a new default Vaadin project, make sure that in your theme.scss file valo theme is correctly imported.

[code]
@import “…/valo/valo.scss”;

@mixin mytheme {
@include valo;

// Insert your own theme rules here
}
[/code]Otherwise, can you please share a small demo project reproducing this so we can see what might be the problem there?
