The layout and padding on the HTTP auth dialog is quite broken. And somehow the action buttons (authenticate, cancel) have swapped positions.
It seems the layout and paddings are much better now with GTK+ from current master, but the buttons are still in the wrong order
There are two problems here, first we are changing the cairo operator when rendering the xcomposite window pixmap without a proper save/restore, so it affects the drawing that happens after that, and second problem is tyhat we are not rendering the gray background in AC mode. I'll submit a patch.
Oops commented in the wrong bug, sorry.
So the only problem was the buttons ordering and it was a GTK+ regression introduced in https://git.gnome.org/browse/gtk+/commit/?id=572e9a04027e213082a5b257e5d662a5daa32667 that I have just reverted in https://git.gnome.org/browse/gtk+/commit/?id=170cb016759c4a949c7cd81291da498395f18fb3 so I'm closing this as invalid since it's not our bug.
I just built GTK+ master and I see zero padding between the Remember Password and the Cancel/Authenticate buttons.
Hm, it depends on the length of the domain....
