Dear Maintainer,
Using gitk on a pretty plain GNOME setup on Debian/buster, the gitk
app is showing the "tearoff" menu item for all the menus. It makes it
really annoying to use the menus. A quick grep shows that gitk's code
disabled it:
~ $ grep -i tearoff /usr/bin/gitk
option add *Menu.TearOff 0 startupFile
$rowctxmenu configure -tearoff 0
$fakerowmenu configure -tearoff 0
$headctxmenu configure -tearoff 0
$flist_menu configure -tearoff 0
$diff_menu configure -tearoff 0
screenshot attached.
