  gnome-shell freeze on key press  while high CPU load

Status in gnome-shell package in Ubuntu:

Bug description:
  This bug happens randomly (once an hour), on keyboard input in
  different apps, ex Firefox address bar, Alfred launcher or Gnome

  I could not find steps to reproduce (tried reducing keyboard interval
  and repeated keypress following STRs from #1731420 but it did not
  freeze, though CPU use increased).

  System is completely frozen, cannot switch to TTY, but music continues
  to play. Sometimes it logs out but most of the time I have to force
  reboot by long pressing the shutdown key.

  syslog show message : "Key repeat discarded, Wayland compositor
  doesn't seem to be processing events fast enough!" multiple times.

  Looks similar to bug

  Ubuntu 17.10 with Gnome session on wayland.
  Gnome-Shell 3.26.2-0ubuntu0.1
