Seeking help troubleshooting - Random pane movement and layout change when clicking on unfocused terminal (Windows Terminal)

[Lockszmith-GH]

Symptoms

Randomly, when I click on Windows Terminal to regain focus of a zellij session, if the layout has more than one pane, the panes get rearranged in a different layout.
After a while, I've learned that hitting Alt+[/] will cycle through different layouts, then I noticed that while I get the layout back (let's say from horizontal to vertical), the location of the panes changed as well (I believe it rotates, but I rarely open more than 2 panes, so in effect, it mostly swaps).

Most of the time (but not always), I also see some random string on the command line, they all look like broken/partial ANSI codes. Some examples: ;111;34m       2;134;36M

My Setup

I use zellij on all of my Linux machine, either in vanilla or close to vanilla configuration (mostly disabling key-bindings that bug me).
My Linux machines are all running some Debian or Debian based distros, and I ssh into them using Windows Terminal on my Windows 11 desktop.
I keep my software updated, Windows, Windows Terminal, OS and Zellij.

This is happening on all the systems running zellij (TrueNAS SCALE, Ubuntu, Pop!_OS).

Additional Background

I've been using Zellij for a couple of years now.
My use-case is pretty straight forward - I use it as a simple terminal multiplexer with a single named session, it replaced tmux for me mainly for its discoverability and excellent community, while I don't understand everything about it, it has been a very helpful tool for me.

Why reach out to the community about this?

This feels like a bug, although there might be a configuration that can help.
If it is a bug, I'm not even sure it's a zellij bug, it might be a Windows Terminal one. The reason I'm using Windows Terminal came out of experimenting with a bunch of terminals, and it was the best one with a clean tabbed interface that passed all keyboard bindings the way I expected and passing things to/from the windows' clipboard was the easiest for me.

This issue has been constant and appears at random a few times a day (it's annoying), and while I saw others mention issues of similar nature, their remedies or bug fixes have not resolved my issue and none have reported the combination of my configuration.

The Question

• Has anyone encountered such behavior?
• If you're using Windows Terminal, can you please share your configuration?
• Anyone has any tips about how to troubleshoot this properly and collect the necessary details to provide the @imsnif with quality data to help address this?

This seems to be related to click+drag of the mouse, it mostly happens to me when I want to use the mouse to copy to the clipboard

If constant writing to the screen occurs, this issue seems to become worse.
This might be related to Windows Terminal, I'll try WizTerm and see if that happens there as well.
