Hi, using Fedora Linux 41 (Workstation Edition).
Since a fresh install a month ago, and using the dash-to-panel Gnome extension, when I have Firefox running and then open Thunderbird, then the correct icons are shown initially. After a while (eg an hour) I notice that the Thunderbird application icon has changed to the Firefox icon. I then see two applications in the panel both using Firefox icon. I do not know how to reproduce this. It just happens and I do not know how this is happening.
I posted this issue on the dash-to-panel issue tracker and through the help provided, did ALT + F2, rancommand enter “lg” without quotes, then on the window that appears go at the top right and click on “Windows”. Please see attachment.
Furthermore, I installed the Extension package and turned off dash-to-panel and when I press the Windows key to show all windows of all running apolications 1) The icon under the Thunderbird window shows a Firefox icon, and the dashboard show a white dot under each application icon, but there is no white dot under the Thunderbird icon.
The Gnome Extensions are developed independent of the Gnome DE. So, Fedora nor Gnome will support them.
Please look with the developer direct. You could write an issue on Github and link to this topic. So you not have to upload the pictures a second time.
I’m not using dash to panel but saw the issue with a wrong icon on the gnome overview and had issues with my custom made shortcuts because the wmclass of Thunderbird changed.
Maybe @linfan or someone with the permissions can edit the title of this thread to include “Thunderbird”, I believe the issue is only with this application.
