Hi Tmux devs; Commit 35690fb3 by Sean Estabrooks restructures the tty_write function:
http://tmux.git.sourceforge.net/git/gitweb.cgi?p=tmux/tmux;a=blobdiff;f=tty.c;h=5d766761a34054ec407f1ae61577ae9b02c5990c;hp=6d77e897093305376d804348a0098c34b4a043a0;hb=35690fb3a53b340aa127e9e90f5d9dd509cd782a;hpb=1c608031b596f6e92e575a16a7acd56fb3b78f70 There is a small error in one of the tests that breaks redrawing in multi-paned layouts. Note that in the previous code, the test for TTY_FREEZE is done againt c->tty.flags. if (c->tty.flags & TTY_FREEZE) continue; However, in this revision, it is instead being tested against c->flags along with CLIENT_SUSPENDED: if (c->flags & (CLIENT_SUSPENDED|TTY_FREEZE)) continue; This breaks redrawing of panes in subtle ways. To reproduce, open a new tmux session at HEAD of master. Open a new syntax-highlighted Vim document in the window. Split the window with split-window -h, move to either pane, and resize it back and forth with resize-pane -L 5 and resize-pane -R 5 a few times. Eventually you should start to notice sections of the Vim window not resizing/redrawing correctly. I was able to reproduce this in both rxvt-unicode-256color and xfce4-terminal. The attached patch is a suggested fix that resolves the issue above for me. I was brain-dumping in #tmux about this earlier today (as tyrmored), so please ignore my babblings there. --Tom Ryder @ Sanctum
