When running anaconda from the live environment on current Rawhide live images, rendering of pop-up dialogs is kind of odd, with text and buttons spilling over the borders. See attached screenshots. This is with an image I built from today's Rawhide primarily to test efibootmgr 0.7, just noticed this issue in passing.

Yeah I see this too, but only on live images (not boot.iso), and even if I disable lightboxing.
Here, have a reproducer:
from gi.repository import Gtk
dlg = Gtk.MessageDialog(text="This looks terrible",
Okay, on the anaconda side... I need to look at setting dialogs to non-resizeable if that is what we want, and also at setting them to decorated (provided it doesn't look crazy on non-gnome live images). On the GTK side, it looks like there's a legitimate bug here with non-decorated windows. Just try toggling set_decorated in that reproducer.
I don't need a bug report to track the anaconda things I mentioned. I've got a whiteboard.
A bug, no question. But why are you making your dialogs undecorated ?
Fixed in https://git.gnome.org/browse/gtk+/commit/?id=9ed2c8a71988079f94a204d2e7d19d3bcad5c933
Fix will be in 3.12.0 next week.
Closing the ticket; this should all be fixed by now.
