The most relevant log messages I can see are:

  Cursor update failed: drmModeAtomicCommit: Invalid argument

If that happens enough times or at an unlucky time, then gnome-shell has
been known to start freezing one display at a time. To work around it,
just add this to /etc/environment:

  MUTTER_DEBUG_FORCE_KMS_MODE=simple

Or if you would like to debug and find the root cause then don't do
that, instead add:

  MUTTER_DEBUG=kms

so we can see what part of the commit the kernel thinks is invalid. In
the past when we've seen this error it's usually been due to bugs in the
i915 kernel driver. So it's really up to mutter/gnome-shell to handle
the errors and recover. Although evdi (DisplayLink) is also a big factor
in your setup.
