Description Unknown 2017-06-10 21:25:57 UTC
gwenview5-16.08.2-1.1.x86_64 on openSUSE Leap 42.2 shows oversaturated thumbs (perhaps not color managed properly) for images which are properly displayed when viewed otherwise (after double clicking the thumb). It seems to happen for images without color profile or with embedded sRGB profile.

TLDR: I use EIZO CG275W calibrated with ColorNavigator (in Windows environment). FWIW EIZO CG monitors store their calibration LUTs in the monitor hardware. I also have oyranos installed. The ICC profile in Linux is soft-linked to the ICC file on the Windows partition and assigned in KDE through Settings->Configure Desktop->Color Management->Devices. In Color Management settings I have relative colorimetric intent (see attachment). In other programs like RawTherapee or digikam there are no such discrepancies, so I don't think it is related to monitor profile in any way.

Please let me know if there any other settings which I need to check.

Thumbnails are not created by Gwenview, but by the KIO thumbnailer, which unfortunately does not support color profiles yet.
