When I emerge thunderbird with USE=system-icu and start it, thunderbird's toolbar is displayed, but remains completely empty: - No buttons shown (I use buttons with "icons besides text") - No search text entry box The only thing shown is the menu button at the right corner, but it does not work: Clicking it is ignored. Right clicking into the toolbar displays the customize toolbar menu, but the "customize" menu item is grayed out and can't be clicked. When emerged with USE=-system-icu, everything works as expected.
Yeah it was updated to 136.0 recently again, I guess you built it before that. https://gitweb.gentoo.org/repo/gentoo.git/commit/profiles/base/package.use.mask?id=0697bf131eb271c6f8f9dfef3fe5eeafeaf1a8de
