    I have recently upgraded to Q3 2014 Telerik Reporting.  Now I have an issue with the WinForms ReportViewer that I didn't have before.  In the visual studio report designer, I have setup my reports to be 8.5x11 Letter in Landscape mode.  Report renders correctly and prints correctly in the designer.  However, when I render the report in the WinForms ReportViewer, it appears that it is shrinking the report by about 60%.  I have checked all the report settings at runtime and everything appears to be correct.

    Any ideas on why this is happening?

    Here is where I am setting up the ReportViewer to render the report:

    Dim myReport As New JMReports.StoreCreditUsage
    With myReport
        .ReportParameters("StartDate").Value = startDate
        .ReportParameters("EndDate").Value = endDate
        .UnitOfMeasure = Drawing.UnitType.Inch
        .PageSettings.PaperSize = New Telerik.Reporting.Drawing.SizeU(New Telerik.Reporting.Drawing.Unit(8.5, Drawing.UnitType.Inch), New Telerik.Reporting.Drawing.Unit(11, Drawing.UnitType.Inch))
        .PageSettings.Landscape = True
    End With
    Dim instanceReportSource As Telerik.Reporting.InstanceReportSource = New Telerik.Reporting.InstanceReportSource()
    instanceReportSource.ReportDocument = myReport
    ReportViewer1.ReportSource = instanceReportSource

    Hello Terry,

    The issue might be connected to the OS DPI settings on the machine used to generate the report.
    Note that we configured a test machine with different DPI settings, but we did not succeed in reproducing the issue. Thus, we would kindly ask you to render one of our demo reports in the WinForms report viewer and check if the issue persists. The source code of the WinFormsDemo project, which you can use for this test, is located in the Telerik Reporting installation folder: C:\Program Files (x86)\Telerik\Reporting Q3 2014\Examples\CSharp\WinFormsDemo.

    This information will help us determine whether the issue is reproducible with any project and report configuration i.e., if the issue is caused by the system configuration alone, or if it is caused by a combination of specific project/report settings and the system DPI setting.
