No scroll in a Tmux session

avatar

Hi!

I'm having problems with scroll in a tmux session in RDM.

I can't scroll though the output of a process in a tmux session, but it works just fine in the default terminal mac app.

I've recorded a video to show the problem better:

This is my ~/.tmux.conf settings file
set -g mouse on
set-option -g history-limit 99999

Hello,

After investigating the issue, turning off "Force scrolling history when using mouse wheel" in File -> Settings -> Entry types -> Sessions -> Terminal should resolve the problem. Could you please try this and let us know if it works for you?

Hello,

I tried to recreate your issue but was not able to set the history-limit. Could you send us a screenshot of your tmux.conf file? I will copy and paste it to ensure the configuration is the same.

Hi!

thanks a lot for the response. I will lay down steps to reproduce in a more precise way, sorry:

ssh into a linux server. I'm using Ubuntu Server 22.04
create a text file with long content, I've used https://www.lipsum.com/feed/html and created lorem.txt with nano lorem.txt and pasting the content
run tmux to open a tmux session
run cat lorem.txt and try to scroll up, it should show all the contents of the file but instead it doesn't scroll the document, it scroll to the previous terminal while using RDM. Expected behavior is to scroll the contents of the document like in the default mac terminal.

this are the contents of my tmux.conf:

but to be honest the history-limit doesn't matter, even if it's not set the behavior is the same, i believe the default is 5000. The set -g mouse on I believe it's required for scrolling with the mouse.

I recorded another video which I hope better represents the bug:

Yes, that fixed the problem. I'm on mac so the location of the setting was a bit different but found it. Thanks for the support
