Eduardo Rojas Rodríguez (edurojas) wrote : [Snap] GUI not show. Opening Thunderbird snap causes 2 processes to open (Ubuntu 21.04)

In a laptop Thinkpad t14s AMD 4750 PRO (Renoir GPU) with Ubuntu 21.04 (5.11.0-22-generic)

When opening Thunderbird Snap, from GUI menu or from command line, 2 processes are opened, and the program GUI is not displayed.

eduardo@edu-ThinkPad-T14s:~$ pgrep -a thunderbird
9173 /snap/thunderbird/127/thunderbird-bin
9253 /snap/thunderbird/127/thunderbird-bin

Killing the last process allows the program GUI to start fully and be displayed.

Thunderbird Snap version:
Name Version Rev Tracking Publisher
thunderbird 78.11.0 12 latest/stable canonical✓

Here are the jurnalctl -t audit -f logs

Maybe its something with new amdgpu drivers, since in another laptop (thinkpad t460 intel with Ubuntu 21.04) this does not happen.
