Duplicate issue #3951: Tmux not updating screen except the top and bottom rows
Created: 2020-07-11T18:57:26Z
Tmux output should scroll up the screen when I print a new line, but it does not. Interesting, pressing the up key in the less program works, pressing down does not. This sounds confusing, please watch the gif attached.

This issue only exists with Alacritty + Tmux. Everything works fine, in Alacritty without tmux, in Windows Terminal with or without tmux, in Alacritty + Tmux on macOS.
Setting the TERM environment variable does not help with either alacritty, xterm, xterm-256color, screen or even screen-256color
System
OS: Microsoft Windows [Version 10.0.19628.1]
Version: alacritty 0.5.0-dev (9974bc8) (Issue also exists in 0.4.3)
Windows: ConPTY
Environment
Default shell is zsh, but no customized .zshrc was used; no .tmux.conf was used, either. Also, no customized alacritty.yml.

Closing comment (2020-07-11T19:42:25Z): You could also try the TERM cygwin that helps with some issues, however I suspect this is a Windows PTY bug.
Can you reproduce this with both ConPTY and WinPTY?
I highly doubt this is related to #2576, since this seems much more like a Windows PTY bug.
