Code which works in CEFSharp V126.2.180 does not function properly in V127.3.50 and above

[Spartan-Hex-Shadow]

Hi there,

Are there any big code changes (apart from the switching of the Cef.IsInitialized from a bool to a nullable bool) that would cause code that functions properly in V126.2.180 of CEF to fail in V127.3.50 and above?

Mine is a WinForms application which in V126.2.180 launches a browser window and loads the URL provided from a WSL file and functions perfectly as expected. In V127.3.50, it launches a browser window but its all white, and then it closes after a couple of seconds. The only code i changed was switching the Cef.IsInitialized to a nullable bool, that's it.

Yes, major upstream changes.

Check your log file for errors

Check your log file for errors

This is what my cef.log printed. Note, as stated, this issue does not occur in V126, but starts in 127

This is what the cef.log printed
