Mouse scroll/click not available in tmux on wsl (windows 10)

[pszypowicz]

I think this is related to the #329

Details

• Browser and browser version: Firefox 78
• OS version: Windows 10
• xterm.js version: 4.8.1

Steps to reproduce

1. Run demo on windows
2. In shell open wsl
3. tmux attach
4. set -g mouse on
5. scroll does not work
6. split the window
7. changing windows with LMC does not work

It seems to work for me:

What version of Windows 10 is this?

[Tyriar]

I tried using wsl/tmux on the demo in Firefox and it gave the same results.

[pszypowicz]

I have insiders preview enabled (the build version is: 19041.388), so maybe that's the fault? I will try it on the laptop with stable release.

I'm on Microsoft Windows [Version 10.0.19041.421] 🤷

[pszypowicz]

Are you using the wsl2 version too?

[Tyriar]

Yes I'm on wsl2 as well.

$ cat ~/.tmux.conf
set -g mouse on

$ tmux -V
tmux 2.8

[pszypowicz]

On Ubuntu 20.04 I have

$tmux -V
tmux 3.0a

and on 18.04:

tmux 2.6

Does not work on neither. I will try to trim my tmux conf for testing.

What distro are you using?
By the way, thanks for helping!

[Tyriar]

I'm on Debian, which should act the same as Ubuntu.

[pszypowicz]

So I just installed debian image on both computers I own (one windows Insiders Preview and WSL2, and one Stable and wsl1). Neither worked. Also, debian was clean with only tmux installed + tmux.conf with mouse setting. Also it does not work for me in the VS Code, which is my goal (and the reason I'm so envy to see your screencast :D )

Do you have any idea, what else may cause it?

[Tyriar]

@pszypowicz what happens when you click? Does it do a regular selection?

[pszypowicz]

Yes, it's just a regular selection, as I would not have mouse setting on in tmux at all. And if I try it directly in the {cmd, powershell, terminal} -> wsl -> tmux then everything works as expected. Just xterm does not work for me (and vs code as a result)
