Newby to Darktable help.
I export my photos take with Cannon camera in raw to Darktable 3.0.1 and then just Auto Crop and add a watermark and export to my Linux Mint 20 Cinnamon computer.
In the default file manager( Nemo), my thumbnails of the exported puictures are green.
If I open then picture then colour is fine, but then thumbnails are green.
About as green as I am with Darktable.
When i open then folder, for a brief second the colour is correct and then it changes to green.
Any ideas where I can start to fix this?
