After sending a message, 2 red dots stay on Ubuntu dock and clicking on Thunderbird icon freezes everything

[Valeryan24]

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. 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 reported the bug on Ubuntu :

Bug seems correlated to Wayland, also:

the same issue for the past 3+ months here

Same here

[fred06]

same here. Each time I send a message with Tbird, another dot appears in the dash, even when Tbird i completely closed (verified with ps).
Another effect: as soon as the first message is sent, "Alt+Tab" (to switch between windows) doesn't work any more, I have to use "Super+Tab".
NB: this annoying behavior appeared in ubuntu 21.04, and still exists in 21.10.
