Description
OS: MacOS Mojave
Steps:
1- Register a log message handler (qInstallMessageHandler) that uses std::cout to print log messages:
std::cout << msg << std::endl;
2- Run the application with debugger attached in QtCreator and observe the Application output pane
Outcome: Messages start printing but as time passes they become delayed
Expected: Messages are shown in output pane with minimal delay
Notes:
- Running without debugger attached shows no delays in Application output pane
- Printing the message in a file shows no delays for one observing the file with tail
- Delays are not observed with MacOS High Sierra
