For me in 20.04, bug is definitely still present. I have earlyoom active, and

activates and nukes a few things, including Firefox, which brings back
interactive response. It also killed Chrome and Remmina, which was

Use Ubuntu 17.10
Open a Wayland session
Start Firefox
Press F11 repeatedly
--> The System freezes
ProblemType: Bug
Yes, sorry. I can confirm the bug exists in 18.04. It is trivial to
reproduce, which is unusual :(
When the screen freezes multiple process start spinning:

Since you have applied the workaround from bug 994921 already, one of

I've had a look at your crash files and unfortunately they do not
contain stack traces we can read yet. Sometimes they do in plain text...
Uploading the crash files with the 'ubuntu-bug' command should fix that,
allowing robots to do proper retracing on them.
Asking other people to reproduce such
Because I did not want to leak any personal data in the crash files, I
reinstalled an Ubuntu 17.10 on another hard drive to have a fresh
generic installation and did the tests there before rebooting on my
regular installation.
There are two crash files, one for gnome-shell, the other one for
OK, thanks. I don't know why that happens. It never fails like that for
me but other people have reported the problem you describe.
Next we try an alternative approach:
1. kill -ABRT `pidof -s gnome-shell`
2. Look in /var/crash for a new crash file (may take a little while to be
written)

I applied the workaround and ran again the command. It seems that

Once you have done that you should find 'ubuntu-bug' and 'apport-cli'

with XWayland.

I found the bug with my main computer which has an AMD gpu. I can
reproduce the bug with the PC I'm using to connect with SSH. I just need
to hold F11 down on Firefox. That PC has a nVidia gpu, so I guess the
problem is gpu vendor independent.

Hello Daniel. Thank you for your suggestion. However, I get this error:

Usage: apport-cli [options] [symptom|pid|package|program path|.apport/.crash

Please install 'openssh-server' and log into the system from another
computer. Now reproduce the freeze and during the freeze, run this from
your ssh login:
apport-cli -u 1749779 --hanging -P `pidof -s gnome-shell`
With some luck that will give us the information we need to debug this.
