[Bug 1932328] Re: Thunderbird under Wayland does not correctly close (or manage) windows

[Xavier Guillot]

Hi,

Since a few weeks, I have a problem with Thunderbird (current version
78.12) and Ubuntu Dock / Dash to Dock in Ubuntu 21.10 :

When I write a new message and send it, after the message window has
closed, its red dot remains near Thunderbird button on the Ubuntu dock -
there are 2 dots: the one of main TB window (receipt box) and a second
one as if there was another window still opened.

But if I switch to another application - Firefox, Gedit, Nautilus, no
matter… - and then with the mouse (left button) click on Thunderbird
icon, desktop freezes completely, I have to manually close the computer
and restart it.

All is frozen, mouse nor Alt-Tab don't work, but if for example
Radiotray was active, I can still hear the audio program live.

If I just roll the middle button on the mouse to switch on Thunderbird
and not click, it doesn't freeze. But to be back on TB main window, I
must before minimize all other applications, then run somewhere in TB
interface (not on Dash button), or roll is useless and doesn't show
Thunderbird.

If I open a window for a new message, don't send it and just close it,
only one red dot stays and no freeze, even with a left button click.

I also report the bug upstream.
