Hello Michael Gilbert.

I recently ran into this issue myself...

Thanks for this suggestion, but maybe you could make sure chromium
always starts with the x11 backend until using the wayland backend is
considered stable enough?

As you might be aware the overwhelming majority of Debian desktop users
are using GNOME which will go switch to wayland by default for 3.22
which will soon be released and is already being prepared in
experimental. (It was already planned for 3.20 but postponed then.)
As the Debian social contract says our users are our priority I thus
think this bug report deserves a higher severity than minor as the
browser by default is more or less unusable now.

Here's a backtrace fwiw (if nothing else might make it easier for search
engines to index this and help others find this bug report easier):
