Any Kitty users tried this? I’ve found Kitty to be exemplary so would be curious if anyone finds this an improvement?

I actually went alacratty => wezterm => kitty. I tried and liked wezterm for a while after alacratty, but after some version, it did something that caused all heavy GPU-using programs(like firefox) to slow down severely, or seize up or something, on multiple computers, after running for more than 24-48 hrs. I had been using the default config, except for my preferred font (the VGA font from https://int10h.org/oldschool-pc-fonts/fontlist/). I unfortunately did not have the time to bisect the options or figure out what exactly was going on, but switching to kitty, cleared up the issue.

I tried looking for a bug reports that matched my symptoms, but found none, and I really did not have the the know-how to diagnose GPU issues, but I'd love to try to help isolate the bug.

It honestly felt like a GPU infinite loop, or GPU OOM issue, because the main CPU was idle, but input and redraws on FF would eventually seize up.

I'm currently using termite. However Termite is no longe rmaintened. I plan to switch to alacratty or kitty. I'm wondering: Why did you choose kitty / wezterm over alacratty?

I started my journey with urxvt, and was seeking better rendering. Alacratty+tmux (with urxvt keybindings) was working well, and I learned to deal with the "auto resize" when moving windows between screens with different DPIs. I tried wezterm from a thread here, and the emoji rendering (a feature I've never relied on before, but nice to have) was better than on alacritty, and stuck with it. Learned to work with it's tabs + extra features, and stuck around for a bit. Liked that I could run the same terminal on Linux + Windows.

I liked wezterm, and it's flexibility, but like I mentioned that GPU bug was killer. I'd have love to help diagnose it, but I'm not sure where to begin. Kitty did most of what wezterm did, and I just stuck with it since. The timestamp on my kitty.conf is 2021-09-11, so it looks like that was the last time I had to tweak it after starting to use it, and I'm happy thus far.

Wezterm has more features and for me being written entirely in Rust made it easy to send a bug fix patch. Kitty however seems to have a noticeably lower latency at least on mac.

I agree… I’m using Kitty and am very satisfied with it. I haven’t tried this one yet, though.

I found kitty faster on my system

As I said in another comment, I tried to use WezTerm a few days before switching back to Kitty for the poorer performance. I ran a few benchmarks and discovered if Kitty takes 1, Konsole takes 2 and WezTerm takes 2.5 (using the same fonts and font sizes.)
