On my large (43"/4K) monitor, tmux resurrect always fails to reconstruct panes properly

[mattphillipskitware]

All the windows in a session will be recovered when tmux is resurrected, but the panes within them are often misaligned.

I save at 80columns per terminal, so this gives me a session that, per window, is 5 panes wide with each subdivision containing 1-4 panes. When I recover, many of the panes will be missing and the remainder will be strongly misaligned. I spent several minutes adjusting things after every recovery and it's pretty annoying.

How I save it:

and what I get back:

With 10+ windows, this is indeed a lot of panes total, but I don't think it's overloading my 32GB RAM system (Ubuntu 16.04/18.04), rather I suspect some tmux process is timing out before a given window can be redrawn properly. This doesn't happen with smaller sessions. Anyone know how I can get things working correctly for my case?

Hey,

I have known about the "window misalignment" problem since the plugin was launched. As you said, it only shows up with multiple panes in a single window. Unfortunately I never figured why, and I tried. This is the example data we get from tmux itself about pane size and position: 7d0a,204x58,0,0[204x29,0,0,100,204x28,0,30,101]. tmux-resurrect saves this data and passes it back to tmux on restore. Since tmux-resurrect is just a temporary data store, and tmux does the work, my hunch is the bug is somewhere in tmux itself.

As for "panes missing" problem: I never had this and this is a bug.
