Cefsharp.Winforms update from version 103.0.80 to 134.3.90 causing sizing display issues in .Net Framework Windows Application

[tsveick]

Hi,

I am using Cefsharp.Winforms in my .Net 7 Framework Windows Application and I am updating my version to 134.3.90 due to vulnerabilities in the older version(103.0.80). When updating my version to the later version all the font sizes and control placements are off in my application. When I originally implemented cefsharp in my application, I had the same issue when I set EnableHighDpiSupport , and when I set 'disable-gpu-compositing' and removed the EnableHighDpiSupport it fixed my issue. How can resolve this issue on your latest version?
To clarify further, it seems that cefsharp is making my applcation DPI aware and my application cannot handle being DPI aware, is there a way to turn off the DPI awareness?

Thank you for your response!
I was able to resolve the issue by setting the dpiawareness to false in code. My application is in vb.net, so I ended up finding similiar code which I used to resolve the issue.

Module DpiAwarenessHelper
    <DllImport("shcore.dll", SetLastError:=True)>
    Public Function SetProcessDpiAwareness(value As ProcessDpiAwareness) As Integer
    End Function

    Public Enum ProcessDpiAwareness
        Process_DPI_Unaware = 0
        Process_System_DPI_Aware = 1
        Process_Per_Monitor_DPI_Aware = 2
    End Enum

    Public Sub SetDpiAwarenessToUnaware()
        Dim result As Integer = SetProcessDpiAwareness(ProcessDpiAwareness.Process_DPI_Unaware)
        If result <> 0 Then
            Trace.TraceWarning($"Error setting DPI awareness: {result}.")
        End If
    End Sub
End Module

I am also having another issue, when loading my browser on the later version, the browser keeps trying to load and keeps blinking, and it can't manage to finish loading the form as it keeps trying to reload. Would you know what the issue would be?
This is my current cefsharp settings:

            CefRuntime.SubscribeAnyCpuAssemblyResolver()
            Dim settings As New CefSettings()
            settings.CefCommandLineArgs.Add("disable-gpu-compositing", "1")
            settings.CefCommandLineArgs.Add("disable-gpu", "1")
            Cef.Initialize(settings)

Upon further research, it seems like the endlessly reloading issue is an issue introduced in version 131.2.70 (it works properly on version 130.1.90) and an issue specific to my url. When trying different urls (ex.github.com/cefsharp), it was able to load properly, and when trying to go to my url (using Chromewebbrowser.Load("https://partner.cardknox.com/login")) it goes into an infinite loop. Here are the logs of the loadingStateChanging loading and finished loading events with the 2 urls I tried, do you have any insight on this?

Try testing with https://github.com/cefsharp/CefSharp.MinimalExample

If that works in the MinimalExample then it's something specific to your implementation. If it doesn't work then you will need to discuss your problem on https://www.magpcss.org/ceforum/viewforum.php?f=6
