It may be a bug in the LIB. I would like to help you debug, but I am powerless to do so...

SCefBrowser only has a declaration without source code, so I cannot locate where the problem is within it.

Did you use a custom source code engine? Did you optimize the official source code? Nick Pruehs ***@***.***> 于2024年12月21日周六 04:56写道：

Hey @aSurgingRiver , yes, we're building the engine from source, but we've only got very minor modifications. Anything specific to look out for?

If the header file under the public engine source code is modified, it will cause abnormal operation errors.
