Describe the bug 【Bug描述】

使用了113、109CEF版本都出现这个问题。 然后就是断点在调用CefShutdown();后系统出现进程残留。而且启动测试程序必须加入 config.addCommandLineSwitch("single-process"); 否则会出现GPU 错误问题。 这个退出进程残留的问题我看已经提交修复了代码了，不知道为何还会出现这个问题

void QCefContextPrivate::uninitializeCef() { logI("QCefContextPrivate::uninitializeCef()-begin"); if (!pApp) return; logI("QCefContextPrivate::uninitializeCef()-1"); pAppDelegate = nullptr; pApp_ = nullptr;

// shutdown the cef CefShutdown(); logI("QCefContextPrivate::uninitializeCef()-2"); // clean job object if (windowsJobHandle) { logI("QCefContextPrivate::uninitializeCef()-3"); ::CloseHandle(windowsJobHandle); windowsJobHandle_ = nullptr; } logI("QCefContextPrivate::uninitializeCef()-end"); }
