mosh is neat, but I've mostly switched back to good'ol SSH over Tailscale due to various rendering bugs caused by client-server mismatches as well as the lack of port forwarding.

Basically mosh attempts to synchronize the state of the terminal which is made up of character cells. It sounds simple until you realize that unicode and fancy escape sequences exist, and the behavior of the client and the server must match otherwise you get weird misalignments that are difficult to debug:

- Unicode 9+ changed character width computation a lot, but macOS `wcwidth` still follows the old algorithm. Let's patch it: https://github.com/mobile-shell/mosh/pull/1289

- There is no support for strike-through and dimmed styles. Let's patch it: https://github.com/mobile-shell/mosh/pull/1059

- What about underline/undercurl? Let's patch it: https://github.com/jdrouhard/mosh/commit/aff5e1c3db9f061deb2...

- Some emojis don't take up two cells as expected? Again, let's patch it: https://github.com/jdrouhard/mosh/commit/b31161ab311c7b6e306...

- ...

You really need those patches to have a good experience, and popular mosh clients like Blink on iOS incorporate them in their builds. However, things look wonky if you don't use the corresponding server builds, and you don't want to dig through layers of abstractions to find out why selecting lines in a specific file in neovim causes everything to become a jumbled mess every so often.

There is no end in sight for those patched to be merged upstream, no end in sight for distros to ship new versions, and no end in sight for protocol changes to make state synchronization more resilient. So, back to SSH we go...

Edit: Fixed wrong link for underline/undercurl patch
