I encountered a strange problem  developing a Nikon raw file with 
digikam 3.0.0-beta2 which did not occur under digikam 2.9:

Under digikam 3.0.0-beta2 (latest version from git) a pattern of a faint 
rectangular lattice of fine lines occurs over the entire .JPG that was 
produced from the .NEF file. This does not happen when using digikam 
2.9, nor do I see this pattern when developing the raw file by 
rawtherapee or darktable.

produced by digikam 2.9 and digikam 3.0.0-beta2 from the following website:

JPG digikam 3.0.0-beta2: 

Since the web-page is not open for directory search you have to specify 
the full urls when using wget for download.
Caution: the files are huge since they were taken with a NIKON D800 
which has a 36 Mpix sensor.

I used the same settings in digikam 2.9 and 3.0.0 when developing the raw.
I am wondering what the reason may be for this unacceptable result in
