Screenshot Preview Canvas

SUMMARY
NEF Files from a Nikon D800 and from D850 are not shown in the canvas (Preview and Light Table) - Canvas stays "grey" while thumbnails of NEFs are shown.
When trying to process these NEFs to jpeg, a very small image is shown in the image Editor and as a result a low resolution jpeg  (160x120) is created.

STEPS TO REPRODUCE
1. Import RAW from Nikon to Filesystem
2. Refresh Albums
3. Goto to Thumbnails View and Doubleclick on Image OR go to Preview and select Image 

OBSERVED RESULT
Grey Screen - Image not shown

EXPECTED RESULT
Display of picture (probably the jpg which is embedded in the RAW).

SOFTWARE/OS VERSIONS
Windows: 
macOS: Big Sur 11.6
Linux/KDE Plasma: 
(available in About System)
KDE Plasma Version: 
KDE Frameworks Version: 
Qt Version: 

ADDITIONAL INFORMATION
Nikon NEF File from a Z50 are shown correctly in preview, but the image editor produces also only a 160x120 pixel jpeg.
Comment 1 Maik Qualmann 2021-11-06 07:24:45 UTC 
The problem here cannot be reproduced with a D850 sample from the web, neither with Linux nor with Windows. digiKam doesn't have any problems with RAW images from the Nikon Z series either, since I use Nikon myself. We need a log of the output of a terminal when you try to load a RAW image into the Image Editor. It is also described here for MacOS:

Comment 2 Maik Qualmann 2021-11-08 12:12:02 UTC 
Gilles,

Can you post a debug log from the MacOS Terminal, from the start to the loading of a large RAW file (can also be ARW)? I want to see whether the memory information is correctly recognized.

Comment 3 caulier.gilles 2021-11-08 16:55:40 UTC 
Hi Maik, 

I can reproduce the dysfunction under MacOS BigSur and last 7.4.0 daily build. I used the D800 NEF files available here :

http://www.rawsamples.ch/index.php/en/nikon

Thumbnails are fine, preview is broken, and editor loading is a very small version. Note that libraw code used in background is the current implementation from github. Exiv2 is last stable 0.27.5.

Comment 4 caulier.gilles 2021-11-08 17:00:06 UTC 
Maik,

You are right the amount of RAM detected do not work when a NEF try to be open :

...
digikam.general: KMemoryInfo: Platform identified :  "MACOS"
digikam.dimg: Error to get physical memory information form a recognized platform
digikam.dimg.raw: Failed to allocate memory for loading raw file
...

Full log when NEF is open :

digikam.dimg: "/System/Volumes/Data/Users/gilles/Pictures/NEF-D800/RAW_NIKON_D800_14bit_FX_LOSSLESS.NEF" : "RAW" file identified
