How do I provide log files when asked?
osu! outputs a lot of information while running about its current state. You can provide these logs when troubleshooting issues. They can usually help in diagnosing and resolving problems which may otherwise be very hard to track down.
In order to get full log output, you first need to change your release stream to either Beta or Cutting-Edge. Full logging is not available on the stable releases as it has a very minor performance impact.
After replicating your issue, you can find the logs in your osu! folder.
Click the options button on the main menu.
Click the "Open osu! folder" button.
Locate and enter the Logs folder.
Select the log required and upload it somewhere publicly available (or attach it to your email).
