Comment:
The tmux issue is caused by gomuks deciding instead of using what's in the TERM environment variable ("screen") to change it to "tmux" internally when the TMUX environment variable is found. On Void the problem could be mitigated by including a tmux entry for the terminfo database, although I think the proper way of solving this would be to simply respect the TERM setting and not use something different instead. Of course having the tmux terminfo on Void when tmux is installed might still be desirable.
I've also commented on the bug mentioned above ( https://github.com/tulir/gomuks/issues/250 ) and sent a pull request to fix that issue.
