After fresh Kinoite 44 install and update, no opportunity to choose previous ostree

Previously, at boot, Kinoite showed a menu of at least two deployments (aka images): current and previous, plus any pinned images. Now, it shows just the current one, blanks, shows it again, then boots. This violates the expectation that one can roll back if a new image fails.

rpm-ostree status shows today’s and yesterday’s images. How can I restore correct boot functionality?

Further searching led me to add a user.cfg file in /boot/grub2 that simply says: “set timeout=5”. This makes the familiar bootloader menu appear again – hooray. Booting is still a bit odd: I see a black screen with a blinking cursor upper left. That goes away, then reappears, then booting occurs normally. It still feels as if something is not as it should be. Any thoughts would be welcome.
