I narrowed this down by doing a bisect dist-upgrade with disk snapshots. I.e. take a snapshot, manually upgrade a few packages, reboot, test, rinse, repeat. The only packages left are the three binary packages mentioned in the bug report. With the snapshot before upgrading those packages, Alt-backtick works. I've verified that after upgrading just these three, the regression occurs.
