---------------------------------
Summary: 【SSH】Exceptions occur when using vim, top, and other
commands to roll back the buffer
Key: GUACAMOLE-1633
URL: https://issues.apache.org/jira/browse/GUACAMOLE-1633
Project: Guacamole
Issue Type: Bug
Components: guacamole
Affects Versions: 1.2.0
Reporter: wengcy

In SSH sessions, when you run vim, top, etc., the displayed data overwrites the
recent rollback buffer.

⬆️ The image above shows the rollback buffer before I used vim, when the
rollback buffer should hold the data from ll.

⬆️ However, after the vim command is used and the exit, the echo generated by
ll command in the rollback buffer has been overwritten by the vim command.
I know that the last page of data should be preserved after exiting using vim,
but the data in the previous rollback buffer should not be lost, and I feel
that this part of the processing like secureCRT is what we want.

⬆️ Just like this, after I use the vim command and exit, the previous ll
command output will still exist, and the vim command will retain the state of
the last screen before exiting.
