Update from CefSharp 103.0.9 to 107.1.40 results in empty web view in Wine expect URL, what am I missing?

[tarasis]

Hi I'm trying to figure out what I need to install (if particular version of .net or .net core). I understand that you likely don't do support for Wine issues, and certainly not Playnite. But you might be able to provide insight that I need to try and fix the issue.

Playnite swapped from using CefSharp 103.0.9 in 10.3, to 107.1.40 in 10.4. In 10.3 it had a working Web view when Playnite was run in Wine (it currently only has .net 4.8 installed). However, when upgrading to Playnite 10.4-10.18 the web view is empty EXCEPT for the url. ( The change JosefNemec/Playnite@af95d5c )

This suggests to me that I am missing something in the Wine install that would help CefSharp's web view work.

Is there any particular packages I should install?

You can have a look at https://github.com/cefsharp/CefSharp#release-branches

If M103 worked then you likely have everything required for M107.

Your best bet would be to see if there are any errors in the CEF log.

• https://github.com/cefsharp/CefSharp/wiki/Trouble-Shooting#log-file
• https://cefsharp.github.io/api/113.1.x/html/P_CefSharp_CefSettingsBase_LogFile.htm (There is a command line arg listed)

https://github.com/cefsharp/CefSharp.MinimalExample is the CefSharp sample application, you can try test it directly.

Thanks for the pointers @amaitland, very helpful.

I've downloaded and compiled the MinimalExample but I can't get it to run in Wine.

Playnite doesn't seem to have a log file for CefSharp.

Trying to run cefyclient.exe from cef_binary_116.0.19+gc6a20bc+chromium-116.0.5845.141_windows64_client.tar.bz2 crashes, I have downloaded the debug symbols for the release, but the program error dialog hasn't finished "Loading detailed information".

Will need to sit and have a proper look at this, possibly custom compile playnite if it has logging of Cef disabled.
