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 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.
