  The status bar in a high dpi environment, incorrectly calculates vertical character spacing and cuts off the bottom of descending characters.

  Hi Prabhat,
  
  All controls are most recent. Win 10 pro and VB most recent. DPI 144. The problem arises when the status bar visual style is set to Custom
  
  Thanks,

  Hi Prabhat,
  
  My vs dpi environment is set for high dpi. I use the following sub Main for the app Startup object. What you are doing (I think) is letting windows scale your app to the higher DPI, which leads to a fuzzier UI. Also, if you scale your main display while developing, you should observe the problem.
  
  Add the below

  Module moduleGeneral
      '*make app dpi aware*
      <STAThread>
      Public Sub Main()
          'dpi awareness
          If Environment.OSVersion.Version.Major >= 6 Then
              SetProcessDPIAware()
          End If
          Application.EnableVisualStyles()
          Application.SetCompatibleTextRenderingDefault(False)
          'load main form
          Dim f As New Form1
          Application.Run(f)
      End Sub
      <Runtime.InteropServices.DllImport("user32.dll")>
      Public Function SetProcessDPIAware() As Boolean
      End Function
  
  End Module

  Hello Kingman,

  Yes, we can observe the issue as shown in your attached screenshot.

  If it is a bug then developers will probably fix it and if there is any implementation issue in the code then we will let you know accordingly.

  Hello Kingman,

  At our end we noticed that the issue exist when changing the Font size of the item in the Statusbar, just changing the DPI with default font does not create any issue at our end.

  As per the developers the height of status bar is constant and scaled using DPI only and it doesn’t scale on font size.

  As you are facing the issue by changing the DPI only so can you please share a stripped down sample replicating the issue so that we can forward it to the developers.
