That sounds really frustrating!
I will say that at endgame, the Hector lecture videos are considered the gold standard for guide videos and tend to be the most commonly used PF strats, and those videos do actually explain the mechanics in detail, with diagrams of how the attacks go out. So while I hope your relationship with your static improves, or you find a better one, once you reach endgame, you should hopefully have a better chance at learning the mechanics either way.
I use iTerm’s tmux integration all the time and would find it incredibly difficult to switch to another terminal emulator that doesn’t have it.
