wayland_debug_log

Description of problem:
When running our desktop automation tests under Wayland - via python3 - the wl_display will sometime attempt to delete the same display twice and the communication between client(python3) and compositor will end with message: Gdk-Message: 13:44:53.888: Error 22 (Invalid argument) dispatching to Wayland display.

Version-Release number of selected component (if applicable):
mutter-40.0-5.el9.x86_64

How reproducible:
Not 100% but eventually will appear.

Steps to Reproduce:
Do not have step by step reproducer. See attachment.

Actual results:
Gdk-Message: 13:44:53.888: Error 22 (Invalid argument) dispatching to Wayland display.

In attached log you can see the attempted delete being done twice and error being thrown:
[2290116.343] wl_display(30)
[2304123.380] wl_display(30)
[2305128.434] wl_display(wl_display@1, 0, "invalid object 30")


Expected results:
No error in journal and the communication between the client and compositor not being ended.

Issue filed upstream as it can be reproduced on Fedora 35 also https://gitlab.gnome.org/GNOME/mutter/-/issues/1797
Comment 3 Michal Odehnal 2021-09-08 09:12:28 UTC 
I am no longer able to reproduce the issue with the fix provided by Olivier in https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/77 , he made a scratch build for rhel-9 which I run on multiple machines and multiple test suites and not a single occurrence of this issue was found.
