Public bug reported: This bug happens randomly (once an hour), on keyboard input in different apps, ex Firefox address bar, Alfred launcher or Gnome Overview.
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 https://bugzilla.gnome.org/show_bug.cgi?id=777693 Ubuntu 17.10 with Gnome session on wayland.
