Package: thunderbird Version: 1:78.8.0-1 Severity: normal Tags: patch Dear Maintainer,
The thunderbird.desktop file contains `StartupWMClass=Thunderbird`. This is incorrect as the Thunderbird window has the WM classes `Mail` and `thunderbird` (lowercase): $ grep StartupWMClass /usr/share/applications/thunderbird.desktop StartupWMClass=Thunderbird $ xprop WM_CLASS [click on the Thunderbird main window] WM_CLASS(STRING) = "Mail", "thunderbird" This impacts some startup detection logic, and most noticeably bamfdeamon which then fails to match windows to the right app. Note that there *is* apparently a Thunderbird window which includes the "Thunderbird" WM class, but that's not the main window, and it kind of looks like a ghost window (other details are funky, including WM_NORMAL_HINTS specifying a 10x10 window, no icons, etc.): $ xprop -name Thunderbird WM_CLASS WM_CLASS(STRING) = "thunderbird", "Thunderbird" In any case, this window also includes the lowercase class, so would be matched just as well by it. Attached is a simple patch that lowercases the StartupWMClass in the desktop file, which fixes bamfdeamon window matching and doesn't seem to otherwise cause issues. This affects e.g. mate-dock-applet as it is a bamfdeamon client.
