It appears in meta_window_set_stack_position_no_sync that:

  g_return_if_fail (window->stack_position >= 0);

is non-fatal and has been that way for almost 10 years.

This means whatever freezes or crashes you are experiencing are happening somewhere else. Everyone please follow the instructions in https://wiki.ubuntu.com/Bugs/Responses#Missing_a_crash_report_or_having_a_.crash_attachment and open new bugs with your findings.
