Can you send us your configuration of nginx/ openresty? We’ve checked on the fly and didn’t encounter any issues.

It would also be useful to have system logs(journal) to check why Gnome is playing up. You could try enabling virtualgl, or use an alternative desktop environment, lightweight as  XFCE or LXDE.
