Bug 418519

SUMMARY

ANSI code CSI n E means to go down n lines, then go to the beginning of that line.

ANSI code CSI n F means to go up n lines, then go to the beginning of that line.

Konsole is not handling these ANSI codes properly (or at all).  I have tested with Gnome terminal and xterm, and they work as expected, so I believe this is a Konsole-specific issue.


STEPS TO REPRODUCE

Run this 2 line bash script:

clear;echo -e "\n\n\n\n\n";
echo -e "Second line\e[1FFirst line\e[2EThird Line\n\n"


OBSERVED RESULT

Second lineFirst lineThird Line

EXPECTED RESULT

First line
Second line
Third Line
