regarding tmux-sixel #2
Description
Hi. I'm sorry for opening this here, but it's not possible to open an issue in your sixel-tmux repository. And I wanted to communicate to you my experience trying to use your fork of tmux.
I was happy to find your project since I'm working a lot with sixels now, and I'm also dependent on tmux... I've compiled it and unfortunately it doesn't work at all for me. I'm using linux Mint 20.1 with a 5.10 kernel.
I've tried it with many terminals (alacritty, xterm, xfce4-terminal, kitty...), and the result is the same, it just hangs without output, and it's not possible to close it with ctrl-c / ctrl-d.
Even more worrying is that after running it every terminal in the system becomes unusable, not showing the prompt after being open. Even the text-mode terminals outside the Xwindows are impossible to use. I have to reboot the machine in order to restore the normal state.
Finally, I've checked this also happens for me with the yatli/tmux fork yours is based on.
