SUMMARY OpenGL ImageViewer and Presentation do not observe the "Monitor Profile from System Settings". (Thumbnails do, Previews do, Slideshow does; under Windows, I have not observed this bug.) Also observed in digiKam version 7.7.0, so apparently not a recent bug. Observed both in VirtualBox and on physical machine. STEPS TO REPRODUCE 1. Open any picture using OpenGL Image Viewer or Presentation 2. 3. OBSERVED RESULT Monitor profile is not applied. EXPECTED RESULT Monitor profile is applied. SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Mint Mate 21.1 (available in About System) KDE Plasma Version: KDE Frameworks Version: Qt Version: ADDITIONAL INFORMATION
The monitor profile is definitely applied in the OpenGL viewer and presentation tool. Tested here with Winows 10 at the moment. What if you manually select a monitor profile in digiKam? Maik
Created attachment 159100 [details] Selection of monitor profile
Maik, as I wrote, under Windows, it works. Just not under Linux. How can I manually select a profile when a system-wide profile exists? Option is greyed out (see screenshot above). (I faintly remember that we discussed this not-being-able-to-manually-choose-a-monitor-profile-if-a-system-wide-profile-exists a long time ago.) Best regards, Harald P.S. I'll be away for the next couple of days so it may take a while before I can respond again.
I just disabled loading of a system-wide monitor profile, so I could manually select a profile. With a manually selected profile, it works. Unfortunately, for me at least, this is no permanent solution since there are other programs that rely on a system-wide profile.
Are you using Wayland or X11? What color management system does Ubuntu use? Maik
Well... I'm only using Linux; I am by no means a Linux expert. As far as I know, it is X11. Color Management System: No idea. My command to set it is "dispwin -I path_to_the_profile", if this is any help. Works perfectly for everything color-related that I use (Xreader, Gimp, RawTherapee etc.), including digiKam's own Thumbnails, Previews, and Slideshow. Just not OpenGL Viewer and Presentation. If this doesn't help, maybe you can tell me how to find out which color management system is used? Best regards, Harald
