If you can reproduce the problem with cefclient then please report the issue on CEF Issue Tracker (Make sure you search before opening an issue). If you open an issue here it will most likely be closed as upstream as the bug needs to be fixed in CEF.

As the problem reproduces with the CEF Sample Application you'll need to raise an issue on https://github.com/chromiumembedded/cef/issues post a link back here

If you are new to the project please read the first few paragraphs ofhttps://github.com/cefsharp/CefSharp/wiki/General-Usage

I have noticed the same issue with version 141.0.110. Tested in two different projects and could replicate it. Any lower version does not have this problem (same project just removed v141.xx and installed v140.xx).

Thanks for creating the upstream issue.

According to the upstream issue, this should be fixed in M142.
