gnome-terminal display lags on keypresses

[John Broadhead]

For a few weeks now my terminal has had an odd hang of up to nearly a second. Usually on the first character I type in a line. I'd say it happens on at least one out of 5 times. At first I thought that maybe it was something that bash was doing in the background, but I went to a bare Linux VT (Ctrl+Alt+F5) and there is never any hangup there.
I also installed and tried stterm, and that doesn't appear to have the same problem at all either.

I tried using the X.org display driver, rather than the Nvidia one (I have an RTX 2770) and that seemed to make the problem go away in gnome-terminal. But oddly, there aren't any similar hangs in games or anything else, just gnome-terminal. Although I think I also experienced something similar in the Ubuntu settings app in text input fields. So maybe there's something in common between those apps?

It's a bug in the mutter package; a fix is on the way. See bug #2059847.
