   Since you're using tmux, a hacky way to workaround this is by using tmux scroll mode CTRL + B [. While in scroll mode, you'll be able to select and copy the text anywhere in the terminal.

   I found a way to solve this problem:

   edit ~/.tmux.conf

   set -g set-clipboard on
   set -g allow-passthrough all

   set -g set-clipboard on
   set -g allow-passthrough all
   

   for me what worked was:

   # Let applications inside tmux send OSC sequences (incl. OSC 52 clipboard) to the terminal
   set -g allow-passthrough on
   
   # Enable tmux clipboard integration (OSC 52)
   set -g set-clipboard on

    I will try that since I've been running into this issue at least since 1.1.42 and just didn't use tmux at all. It's weird though because copying from/to other applications inside tmux on WSL works fine.

    Works! Cheers, kind stranger!

    Have you executed the tmux source-file ~/.tmux.conf pointing to the location of your tmux.conf?
