Description

As described. Sometimes it's lots of text, sometimes it's just tmux;

.screenrc in use:

  startup_message       off             # default: on
bell_msg ""

  obuflimit             20485760 # 10m should be enough.
  defflow               off

Steps to reproduce

1. start screen (install 5.0 from homebrew)
2. start opencode
3. select text on the screen
4. et voila - see screenshot.

The text "tmux;" is not inserted into the textfield - if I type it gets overwritten.
The selected text is copied.
