Description

In Case of Graphical or Performance Issues

Nothing interesting in the log file.

Basic information

zellij --version: 0.19 tput lines: 50 tput cols: 103 uname -av: Linux usah 5.11.0-38-generic #42~20.04.1-Ubuntu SMP Tue Sep 28 20:41:07 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

List of programs you interact with as, PROGRAM --version: output cropped meaningful, for example: gnome-terminal --version: GNOME Terminal 3.36.2 using VTE 0.60.3 +BIDI +GNUTLS +ICU +SYSTEMD

Further information When using the default config file, I setup two tabs with horizontal splits:

  1. Alt+N for a new pane
  2. Ctrl+t,n, Enter for a new tab
  3. Alt+N for a new pane

Then, the following behavior seems non-deterministic:

  1. navigate to pane 1 on tab 1
  2. use Alt+L Alt+H to navigate between panes.

Result:

  • When moving from pane 1 tab 1 to tab 2 using Alt+H, sometimes you land on pane 1 instead of pane 2.
  • When moving from pane 2 tab 2 to tab 1 using Alt+L, sometimes you land on pane 2 instead of pane 1.

After testing it a few times, it seems this happens once every 5 to 10 times you navigate between tabs.

Research direction
Investigate the pane and tab navigation logic in the Zellij source code, particularly in the keybinding handling and state management. Look at the `src/panes` and `src/tab` modules. Reproduce the issue with a consistent configuration and check if there is a race condition or incorrect focus updating when switching between tabs. Review the comments in the issue for any additional clues about the non deterministic behavior.
