In Case of Graphical or Performance Issues

1. Delete the contents of /tmp/zellij-1000/zellij-log, ie with cd /tmp/zellij-1000/ and rm -fr zellij-log/
2. Run zellij --debug
3. Recreate your issue.
4. Quit Zellij immediately with ctrl-q (your bug should ideally still be visible on screen)

Please attach the files that were created in /tmp/zellij-1000/zellij-log/ to the extent you are comfortable with.

The logfile that results from this operation is essentially empty, containing only the text of the original prompt.

Further information
Reproduction steps, noticable behavior, related issues etc

From a fresh (release) build of Zellij running in Wezterm, hold the mouse button with the mouse at one corner, and drag it swiftly to the opposite corner. Zellij lags behind the mouse movement by about 0.5 seconds. Doing further mouse drags back and forth causes Zellij to fall even further behind. If key inputs are entered immediately after dragging the mouse around, the mouse actions are handled, then only after they are fully handled, the keystrokes are handled.

This only happens with Wezterm for me. Alacritty and Konsole with Zellij running on them both have no trouble keeping up with them. And Wezterm by itself, not running Zellij, has no trouble keeping up with my actions either. This only happens for me in Wezterm, running Zellij.

Thanks for the detailed issue, @eaglgenes101 ! I'm going to delve more deeply into it the next time I do a batch of compatibility issues (likely in a couple of weeks), and will ping you if I need help reproducing it.

The latest release of Wezterm seems to have fixed this issue for me. Maybe others have similar issues, but mine is good now.
