I'm trying to use gotop on a cluster computing centos 7 system, but the program can only detect a few CPUs. The right configuration shows like this htop image, 16 cores. The display in tmux is not right but outside tmux is fine.

• Inside tmux
  

• outside
  

• Right config

Just fyi, you can display all the separate cpu cores in the graph with gotop -p. It only shows average by default if there are more then 8 cores.

Thanks for the info. I used gotop -p to display all cores. This doesn't fix the tmux display.

Confirming I've got the same issue with tmux, in both bash and zsh.

By the way, this bug doesn't appear on latest tmux version (2.8).

@wallace11 Did you get this issue on a previous version of tmux tho? I wasn't able to reproduce this with alacritty or gnome-terminal on any version of tmux back to 1.0.

Sorry, I wasn't trying to replicate this on another version...

I do see this occurring on tmux 2.8, at least in Alpine Linux.

Is this a unicode display issue? https://askubuntu.com/questions/410048/utf-8-character-not-showing-properly-in-tmux suggests running "tmux -u" to fix a similar issue.

[cdiener]

Can confirm that running with tmux -u fixed the issue for me.

[lz100]

Confirm tmux -u fixed the issue.
