Bug 424738: Scrollback buffer gets partially deleted after pressing "Ctrl+L"
https://bugs.kde.org/show_bug.cgi?id=3D424738



--- Description ---
Just after a recent upgrade,Konsole doesn't retain the scrollback buffer
correctly anymore and the last X lines of it(where "X" is the row size of t=
he
terminal,24 by default) gets deleted from the buffer after pressing
"Ctrl+L".This happens in a fullscreen(by pressing "F11") terminal window
too.Also the "clear" command makes the buffer disappeared completely.

STEPS TO REPRODUCE:

1. Open the Konsole terminal emulator

2. Issue a command that generates a relatively long output(i.e more lines t=
han
the number of terminal window rows)

3. Press "Ctrl+L" and check the scrollback buffer again
