  • WPF

• What is the expected output? What do you see instead?
  

• To fix it we've tried to put this in the very beginning of the OnStartup method of the App.xaml.cs:

            Cef.EnableHighDPISupport();
            var cefSettings = new CefSettings();
            cefSettings.CefCommandLineArgs.Add("disable-gpu-compositing");
            cefSettings.CefCommandLineArgs.Add("force-device-scale-factor", "1");
            Cef.Initialize(cefSettings);

and added this to the app.manifest:

      <dpiAwareness xmlns="http://schemas.microsoft.com/SMI/2016/WindowsSettings">PerMonitorV2</dpiAwareness>
      <dpiAware>true/PM</dpiAware>

Have you tested with the minimum example? https://github.com/cefsharp/CefSharp.MinimalExample

Based on photo it doesn't look like your application is correctly DPI aware.

Converted to discussion as this is unlikely a bug.

Improvements were made to DPI handling in .Net 5 in version 89 (a big part of the reason we ask thatyou only open an issue if you can reproduce the problem with the latest version which is currently 91)

Don't use force-device-scale-factor when using WPF.

You should confirm your application and the CefSharp.BrowserSubProcess.exe have the same DPI awareness in task manager.
