> it's nigh impossible to eliminate tearing on multimonitor setups with X11,
I haven't seen tearing in longer than I can remember, and can't remember anyone even mentioning it, so I think you're overplaying this point JUST a tad. I tend to use older laptops with Linux, and older screens (VGA, DVI), so maybe that's the reason.
Out of curiosity (not to question), is this on Xorg or Wayland?
I rarely use my external monitor, and I can't even remember the last time I had used it in portrait mode, so these comments made me realize there could be use cases (and not just hardware or drivers) that trigger tearing that I just hadn't encountered. But I just took a quick shot at it, and I didn't see tearing, at least not on YouTube, nor when moving a window around.
I was wondering if I just wasn't very sensitive to tearing, because I haven't noticed it. One setup is a 4K 46" or Dell 30" next to a 4K laptop, the other is 4K 46" with two 1080P wings in portrait.

I hate touchpads.
I don't do PDF editing.
Everything's a tradeoff.
