Preview with focus check is totally broken
Affected version: 2.6.0 (installed/built from gentoo portage)
I noticed the focus check is not working correctly in 2.6.0 while it used to, in 2.2 or so. This is how the preview looks (in both cases I used C-z). It doesn't show anything for all DNG files and also the incorrect spots are the same in every JPEG I tested.
