Oddly, I can no longer reproduce this problem myself. I edited
/etc/screenrc to restore its original contents, but the issue did not recur.

I can't see any package updates since the bug report that would affect
the issue.

If the issue does recur, I will follow the bug reporting guidelines.
Thanks for investigating.
