patch 9.2.0150: synchronized terminal update may cause display artifacts
Problem: When using synchronized terminal output, the internal
output buffer is not flushed before sending the
End Synchronized Update (ESU) sequence. This causes
redrawing artifacts.
Solution: Call out_flush() immediately before sending the ESU
sequence to ensure all pending drawing commands are
contained within the synchronized update window.
