Bug#1070057: mutter: Severe keyboard input lag/pauses

[Florian Cramer]

Package: mutter
Version: 46.0-1
Severity: important
X-Debbugs-Cc: flrncrmr at gmail.com

Dear Maintainer,

In all programs that rely on mutter and/or Gnome/GTK libraries for keyboard
input, I am experiencing severe keyboard input lag/pauses, sometimes for
several seconds. This might be a problem that only occurs in xorg with the
Nvidia driver, and is identical to what has been described here:
https://gitlab.gnome.org/GNOME/mutter/-/issues/3384


   * What led up to the situation?
Update from Gnome/mutter 45 to Gnomemutter 46.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

The problem occurs in Gnome-Terminal, but also XFCE4-Terminal and LXTerminal.
It can be mitigated by using xterm.
