Description

The zoom with the zones in focus (Ctrl-z) doen't seem to detect the zones in focus.

On DNG files, no focus zones are shown, whatever the picture I tried it on.
On CR2 or JPEG files, everything is considered in focus except very large areas of uniform tone/color (like a grey sky f.e.)

I have attached a JPEG which is a very obvious example of the problem. Ctrl-Z says the entire picture is in focus!

Note: Since I have no release on my portraits, I picked that one off the internet as it has a very clear separation between focus and blur and a resolution equivalent to a typical modern sensor (22MP).

Same result: it works on NEF files but says everything is in focus with JPEGs and nothing is in focus on DNGs.
