Description
I'm using mosh 1.3.2 to connect to a mosh 1.2.6 (Debian Stable) server. When using Emacs (24.5.1) with long, truncated lines in one buffer and visual-wrap in other buffers (the notmuch mail client), I get visual corruption: text that should be cleared is put in the first line, the mode line gets screwed up, and similar.
I don't get such corruption connecting to the same tmux session over ssh. I get the corruption both in iTerm2 and in Terminal.app. I don't think I saw that corruption in mosh 1.3.0. I originally observed it with tmux 2.3 in the mix, but have replicated it without tmux.
How can I help debug this?

Research direction
No source file or test is named. Start by reproducing the corruption with Emacs 24.5.1, mosh 1.3.2 over the reported server versions, and compare the same session over SSH and with mosh 1.3.0; done means isolating a minimal reproduction or confirming the version-specific regression with useful debugging details.
