CefSharp Version

71.0.0

Please don't create issues for ancient unsupported versions. The current supported version is M119 (Soon to be M120)

Try the latest version if you can, you can test it out using https://github.com/cefsharp/CefSharp.MinimalExample

If you are unable to upgrade for some reason then try disabling GPU acceleration.

Okay, I will try the latest version.

Also I found the Cef(CefSharp 71.0.0 ) log file has the below errors like,
