Hello Aleksey,

I am sorry to hear that you are experiencing issues with our product. Some of our customers had a similar problem. For that reason, you may test to merge the Resources as low as possible to the ReportViewer. For example:

<Grid>
    <Grid.Resourcves>
        <ResourceDictionary>
        <ResourceDictionary.MergedDictionaries>
            <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/System.Windows.xaml" />
            <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/Telerik.Windows.Controls.xaml" />
            <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/Telerik.Windows.Controls.Input.xaml" />
            <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/Telerik.Windows.Controls.Navigation.xaml" />
            <ResourceDictionary Source="/Telerik.ReportViewer.Wpf.Themes;component/Themes/Green/Telerik.ReportViewer.Wpf.xaml" />
        </ResourceDictionary.MergedDictionaries>
        </ResourceDictionary>
    </Grid.Resources>
<ReportViewer />
</Grid>

Let me know if this resolves the problem.
