tmux vertical split does not work

Hi everyone,

I am a new to freebsd FreeBSD user and I am having problems with tmux. When I split it vertically the text gets shuffled around, I have used tmux in linux and it never did that. Are there any config files that I need to modify? Or is this a bug?, I have tried to google this issue but I have not been successful, any help is appreciated.

Thanks in advance!
 
I am using tcsh, and I don't have x11 installed in that computer so I never tested it in a terminal like rxvt-unicode. I am actually having the same problem as the one shown in this video (I just found it a few hours ago):

I don't know if this matters but I installed tmux from the ports i.e. sysutils/tmux (did not use a package).

The output of env is long and it is not in this computer so I can not copy and paste, but I think the important parts are:

Code:
SHELL=/bin/tcsh
TERM=cons25
MACHTYPE=i386
I would also like to add that the problem occurs when the output of a program is long, for example when trying to read man pages.


Thanks
 
Here, tmux 1.5 has the same problem on real consoles, but works fine in X. This is with FreeBSD 8-STABLE. Could be a bug in tmux, a bug in FreeBSD's syscons, or just a difference between FreeBSD and whatever tmux is expecting.

Edit: the console code is different on FreeBSD 9, and a quick test there didn't show the bug.
 
ok so in conclusion this is a bug and apparently it will be fixed in FreeBSD 9. I will mark this thread as solved. Thank you everyone for your help!
 
It's a bug, but it's not for certain exactly where it is. FreeBSD is going to be around a while, too. It would be good to check with the port maintainer, they may not be aware of the problem.
