Sometime last week, my snap thunderbird package updated to version 128.9.1esr. After that update, clicking on the Thunderbird icon in the dock starts thunderbird under a generic icon that appears on the right side of the dock (showing the dot indicator under it), rather than showing the thunderbird icon with the running indicator under it. I am using X11, fully updated Ubuntu 24.04.2, with Thunderbird installed as a snap. Work correctly until last week. If I start the application manually from the command line, same generic icon appears. (If I start firefox snap from the command line, the firefox icon shows the "running" indicator under it as it is supposed to. Note: Thunderbird IS running and running fine - I have not found any other issues, just this potential regression. Anyone have any ideas? I thought I would post here before filing a bugzilla bug report. I was not able to find any mention of this (or a similar) problem in the last year. Thanks.
