Description

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?

Research direction
Investigate the pane layout restoration logic in tmux resurrect, specifically how it captures and reconstructs pane geometries. Look at the `resurrect.tmux` script and `helpers/` functions that call `tmux list panes` and parse pane dimensions. Compare the saved pane dimensions (from `tmux list panes F`) with what is restored. Consider if there is a race condition or timeout when restoring many panes on a large monitor. Check if the issue is related to the ` t` target argument or how panes are split. Review any related issues or PRs in the repository for similar fixes.
