Fix macOS Crash on Resize

• Enable system fonts
• Disable partial rendering

Enable debug log

• Top Bar Menu -> Three Lines menu (the leftmost one) -> Help -> Report a bug
• Enable verbose logging
• Restart KOReader
• Reproduce the issue
• Open Report a bug again to flush the log to crash.log

Warning

On Android, crash.log is not written continuously. Verbose logging only feeds the in-memory logcat buffer; the log is dumped to crash.log only when you open Report a bug from the menu again. Do this right after reproducing the issue, before the buffer rotates.

Where to find it?

The debug logs can be found in file crash.log:

• Desktop/other platforms: in the KOReader installation directory.
• Android: in <external_storage>/koreader/crash.log.
