ghost compose window with wayland

[Martin Kaistra]

After writing a new email and sending it, gnome still sees the compose window, even though it is really closed.
* Ubuntu Dock has an additional dot next to the thunderbird logo
* Clicking in the top bar on Thunderbird has the compose window listed under "Open windows"
* Using get_windows() in looking glass on the thunderbird app object gets 2 objects of MetaWindowWayland

Even after closing the main window of thunderbird, the ghost window is still there (dot next to thunderbird logo in ubuntu dock), which means Ubuntu Dock is not launching thunderbird on single left click any more.
Right click on the thunderbird logo in this state just opens an action window which doesn't respond to any clicks.
Only logging out and back in seems to restore normal behavior.

This is happening since upgrading to Ubuntu 21.04 and using wayland by default. It doesn't happen 100% of the time, but often enough for me to be able to collect additional information if necessary.

Thank you for your bug report, it seems rather a shell issue getting confused about the status of the windows

[Sebastien Bacher (seb128)]

Could you do
$ apport-collect 1928312
now that it got reassigned that would add the debug informations for right component

doesn't look like there is sensitive information in #8, hope I didn't miss anything ;)

[Daniel van Vugt (vanvugt)]

Thanks for the bug report. Since so many bugs are caused by extensions, please try removing these as a first step:

'<email address hidden>', '<email address hidden>@gmail.com', '<email address hidden>', '<email address hidden>'

Then log in again and verify the bug still happens. If it does then please also try disabling 'Ubuntu Dock' in the Extensions app.

[Martin Kaistra (djfun)]

I disabled the extensions you listed and could still reproduce it. Then I also started to disable the extensions shipped with Ubuntu, it also happens with 'Ubuntu Dock' disabled.

However, at least right now, I cannot reproduce it when 'Desktop Icons NG (DING)' is disabled, so maybe this is the problematic extension?

[Daniel van Vugt (vanvugt)]

That is weird and hard to explain. Can you try toggling back and forth and verify that is the cause?

[Martin Kaistra (djfun)]

I tried a couple of times to enable/disable the Desktop Icons NG extension, logging out and back in and trying to reproduce the issue and, yes, it seems to only happen (and at the moment quite reliably) when the extension is enabled.

[Martin Kaistra (djfun)]

I see this message in journalctl when the issue happens:

meta_window_set_stack_position_no_sync: assertion 'window->stack_position >= 0' failed

not sure though if this is related.

[Cyril Jaquier (cyril-jaquier)]

Exact same problem here but for me it happens with both Desktop Icon NG extension enabled or disabled. This is pretty annoying since the only workaround is to logout and login again. And I use Ctrl+Tab a lot which totally breaks with this bug.

[Daniel van Vugt (vanvugt)]

Yes I think that error message sounds related, but it's already got its own bug 1871262 so let's group it there for now.

[Gyuris Gellért (gellert-gyuris)]

Ubuntu 21.10, Wayland, same error. Disabling 'Desktop Icons NG (DING)' is a working workaround.

[Lulubel (lulubel1060)]

Same problems for me.

And Cyril said: "And I use Ctrl+Tab a lot which totally breaks with this bug."
I confirm but I add: the action window that "froze" is above the dock and mask the menu "activities" and some launchers. So we can't use alt-tab nor the mouse to get around the problem. Because we cannot launch any other application.
