Ubuntu 17.10. With the latest Nightly update, titlebar rendering stopped working. Something that landed between yesterday and today must have caused this regression.

Thanks, will look at it.

Marco, do I understand correctly that: MOZ_GTK_TITLEBAR_DECORATION=client ./firefox - works MOZ_GTK_TITLEBAR_DECORATION=system ./firefox - does not work and your $XDG_CURRENT_DESKTOP is "ubuntu:GNOME" at Ubuntu 17.10.

There's a patch but it needs to be tested and also better fixed the nsWindow::GetScreenBounds() which is for Bug 1423810.

Can confirm the problem with manjaro linux (Arch) Works with MOZ_GTK_TITLEBAR_DECORATION=client doesn't work with MOZ_GTK_TITLEBAR_DECORATION=system $XDG_CURRENT_DESKTOP is "GNOME" Quick fix, add export MOZ_GTK_TITLEBAR_DECORATION=client to .profile

Hm, are you sure the regression range is correct? I did test builds of the latest trunk + reverted those patches but I still see the default system titlebar shown.
