Bug ID: 481294
Summary: Sequence <ESC>[3J is implemented incorrectly (should
erase whole screen AND clear the scrollback buffer)
Classification: Applications
Product: konsole
Version: 21.12.3
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: emulation
Assignee: konsole-de...@kde.org

SUMMARY
According to `man console_codes` the CSI sequence
> ESC [ 3 J: erase whole display including scroll-back buffer
but Konsole implements it as simply clearing the scrollback buffer without
erasing the display.
STEPS TO REPRODUCE
1. Run something to have text on screen and scrollback buffer.
2. Execute following command
printf "\033[3J"
OBSERVED RESULT
Terminal scrollback buffer is deleted but the text visible on the terminal is
not touched.
EXPECTED RESULT
There should be no visible text and the scrollback buffer should be empty.
Tested with Ubuntu 22.04 LTS and Konsole version 21.12.3.
