> [amirsalarsafaei] I downgraded my mutter to 45.0-3ubuntu3 but the
issues persists

Mentioning just in case:

You should downgrade all the packages built from mutter's source that
you have installed, including libmutter-13-0, mutter-common, mutter-
common-bin etc. (Or at least I don't know which one really matters.)

And then you need to log out of your graphical session and log back in,
otherwise the previous mutter keeps running.

I'm pointing these out because this suspected mutter change is the only
relevant that has a reasonable chance of causing the issues, and
multiple people have reported that downgrading fixed the issue for them,
yet you report that it didn't for you. At this point we have to consider
that you might have made a mistake during downgrading, rather than the
bug being somewhere else.

> how to downgrade my mutter to specific version without apt?

I'd download these older packages from packages.ubuntu.com (as you
presumably already did with mutter), install them with `dpkg -i`, and
put them on "hold" (something like: `echo "mutter hold" | sudo dpkg
--set-selections`, and repeat for the other packages).

> an interesting thing is that the gnome-console is fine but other vte
based terminals have severe lag.

gnome-console uses gtk4 (and in turn the gtk4 variant of vte), others
use gtk3 (and in turn the gtk3 variant of vte). (I'm just stating this
as a fact. Don't ask how it triggers the bug to manifest with one but
not with the other, I don't know.)

  There is a noticeable delay in input while using the native terminal.
