ComboBoxItem design problem

[cyr]

We updated to smartGWT 4.0 and now we have problems with the design of the ComboBoxItem.
The Data Area is displaced (see Attachment).
I checked the CSS with an example from the showcase. I couldn't find something different.

Our CSS looks like this:

element.style {
    -moz-box-sizing: border-box;
    background-color: white;
    cursor: default;
    display: inline-block;
    height: 302px;
    left: 0;
    overflow: hidden;
    position: absolute;
    top: 0;
    width: 210px;
    z-index: 203258;
}
.pickListMenuBody {
    background-color: white;
    border: 1px solid #8FA7C7;
}
element.style {
    cursor: default;
    visibility: inherit;
}
element.style {
    visibility: inherit;
}

Has someone the same problem? Or a solution?
