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.
Regards,
Colomban
