picom VS compton

(https://github.com/yshui/picom/blob/next/picom.sample.conf)

Also I took a census and zero founding members of NWA are "straight outta Picom". That's right, you heard it here first: Not even MC Ren is running Picom.

Update: after reporting in picom GitHub repo this is temporarily solved by using --no-frame-pacing. Looks like a recent commit causes this. You can view the discussion here: https://github.com/yshui/picom/issues/1072

Compositor : picom

It looks like this was identified and the repo corrected in Jan (https://github.com/yshui/picom/issues/808) but the NixOS package has not been updated since Nov.

If you have compositing you are likely using picom. You can check if it's running with ps -A | grep picom. I've never dealt with this issue as I don't really game on linux often, but I'm sure there's a solution somewhere in the github docs or issues. Worst case scenario you could always just kill the process with killall picom whenever you're about to game, and re-enable it with picom -b after. Do note though that currently running windows might bug out a bit when you kill/start the compositor.

Picom is broken for me with GLX backend related Github issue.
