I have similar problem. I'm currently using Ubuntu 22.04.4 LTS (x86_64).
Since some days (maybe three?) I see very odd behaviour from programs
running in gnome-terminal (or xfce4-terminal if it does not matter, I
guess the problem is not the terminal itself but VTE probably or
similar? - no problem when using KDE's Konsole for example!). I also
have nvidia's driver.

Some programs "only" have very significant input delay, sometimes like 1
sec or so. However interestingly some programs (most notably neomutt)
has "infinite" delay, ie, it lags behind exactly one key. For example if
I move upwards in the email list, then pressing down still moves up
once. And so on, it seems to be true for all keys. Other applications
running in terminal seems to "only" have more significant delay, but
it's not always consistent. Especially ssh'ing to a remote machine is a
very bad experience now, but even on the local host, without any ssh
involved just the shell, it's very notable.
