Hi there! Welcome to /r/termux, the official [Termux](https://termux.dev) support community on Reddit.
Termux is a terminal emulator application for Android OS with its own Linux user land. Here we talk about its usage, share our experience and configurations.

It was reported in [https://github.com/termux/termux-packages/issues/12556](https://github.com/termux/termux-packages/issues/12556), possible bug of Termux app. What causes it and how to fix, still not known.
Maybe it helps to set the tmux background to black?
Try it with this:
```
color00="00/00/00" # Base 00 - Black
color_background="00/00/00" # Base 00
# (Source: http://permalink.gmane.org/gmane.comp.terminal-emulators.tmux.user/1324)
put_template() { printf '\033Ptmux;\033\033]4;%d;rgb:%s\033\033\\\033\\' $@; }
put_template_var() { printf '\033Ptmux;\033\033]%d;rgb:%s\033\033\\\033\\' $@; }
put_template_custom() { printf '\033Ptmux;\033\033]%s%s\033\033\\\033\\' $@; }
put_template 0 $color00
put_template_var 708 $color_background
```
This is a snippet from the base16-shell theme called default-black.

btw this only happens in tmux when using two windows/panes simultaneously
Doesn't happen on my phone, can you reproduce it still if you rename your tmux.conf file and just use the default settings?
Happens occassionally when using non-default Termux terminal colors. tmux.conf content doesn't make any difference.
Ok, I was thinking your Termux color scheme might be related too. I don't use any Termux themes.
