Arch Linux

Description:
as of now there are some terminal window redraw issues while using mosh with vte terminals. Specifically, after updating the screen there is always a chance that some of the new lines won't be redrawn or will be redrawn partly and incorrectly. It goes away as soon as screen is updated again by moving another window on top of it or just switching to another tmux / screen window in the terminal itself. It is referenced in these vte and mosh bugs:

Steps to reproduce:
Using tmux with panel listing open windows it works for me every time. Just create a 7th window from 6th window: the panel will be showing only 6 with 6th selected, attached screenshot shows it happening.
Another way: just connect to a server using mosh, run a couple of commands to fill the screen and scroll it, clear the screen and repeat if it didn't appear. Sometimes it happens, sometimes not.
