Mike Jumper updated GUACAMOLE-1801:
-----------------------------------
Priority: Minor (was: Major)
> Last line of terminal emulator may repeat when display scrolls
> --------------------------------------------------------------
>
> Key: GUACAMOLE-1801
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1801
> Project: Guacamole
> Issue Type: Bug
> Components: Terminal
> Affects Versions: 1.5.1
> Reporter: yukui
> Priority: Minor
> Attachments: image-2023-06-05-09-25-38-947.png,

>
> When (1) the console continues to output and (2) the scrollbar on the right
> has been scrolled such that it is no longer at the bottom, the last line
> shown on the terminal emulator will be output repeatedly. When the terminal
> is scrolled back to the current view (scrollbar position is returned back to
> the bottom), the screen returns to normal.
> !image-2023-06-05-09-25-38-947.png!
> To reproduce:
> # Open a terminal session, such as an SSH connection.
> # Fill the screen with data, such as with a command like {{ls -l /usr/bin}}.
> # Run a script or command that regularly produces one line of output without
> user interaction (example script shown in screenshot).
> # Scroll up by at least one line.
> # Wait for output.
> # Observe that the last line visible is repeated, instead of off-screen
> output being revealed.
