Hi, Bug: When splitting a tmux pane with <prefix>-<">, under some circumstances, the new pane will not be half the size of the original pane but rather as big as possible, leaving only a single line for the original pane at the top.
To reproduce: Start tmux, split the initial pane in two with <prefix>-<"> and change the layout to two side-by-side panes with <prefix>-<space>. Then split one of the new panes vertically with <prefix>-<"> or "tmux split". This does not seem to happen if the layout isn't first changed with <prefix>-<space>, and it only seems to happen if there are only side-by-side panes (no top/bottom split). I *think* this was introduced during November. The bug is present in -current as of this morning. I've reproduced it over SSH from both PyTTY on Windows and iTerm on macOS, as well as while logged in on the physical machine in xterm and in the console (with no X-Windows running). Sometimes, too, when connecting to an existing tmux session, the session will immediately exit (the tmux server dies), or the lower part of the tmux window will be unused (the panes are restricted to the upper half), even if no smaller client is connected to the tmux server at the time. This too started happening around the same time but I can't reproduce it reliably. My tmux configuration is set-option -g history-limit 5000 set-option -g mouse on set-option -g prefix C-a set-option escape-time 100 set-window-option -g allow-rename off set-window-option -g automatic-rename off bind-key C-a send-prefix unbind-key C-b TERM is "screen" in the tmux session. -- Andreas Kusalananda Kähäri, National Bioinformatics Infrastructure Sweden (NBIS), Uppsala University, Sweden.
