What to include

Where the log is

Litho writes logs/litho.log in its settings folder, beside ui.json and prefs.json.

System Log folder
Windows %APPDATA%\Litho\logs\
macOS ~/Library/Application Support/Litho/logs/
Linux ~/.config/litho/logs/ (or $XDG_CONFIG_HOME/litho/logs/)

Each start moves the previous log to litho.1.log, and that one to litho.2.log. The log from a run that crashed survives the next start, so attach litho.1.log if you have restarted since. The file stops growing at 16 MiB.

More detail in the log

Set the environment variable RUST_LOG to debug before starting Litho to log more. The default is info for Litho's own parts and warn for everything else.
