For the longest time, the workflow I’m going to describe here worked just fine until a couple of days ago when for reasons unbeknownst to me it didn’t anymore.
Whenever I would do a fresh install, I would fire up DisplaCAL, calibrate my display and subsequently install the resulting .icc colour profile as system-wide. It would, very predictably, reflect this as correct when checking Gnome settings - the profile was loaded and activated.
I would then only need to check “Use system monitor profile” in both RT and GIMP and that was that - consistent colour across all apps.
However, this stopped being the case a couple of days ago and I don’t know why. Let me describe what is going on now.
Gimp is fine, as is Firefox and gthumb - they are all displaying images in the same maner, as expected.
It’s just RT that seems to behave strangely. Thumbnails in the browser window and the film-strip in the editor view are displayed with very saturated and vivid colours, nothing like they’re supposed to look like. I can, however, make it display correct colors if I switch the working profile from the default ProPhoto to sRGB or if I enable Soft Proofing underneath the main view in the editor. All this is not something that I had to do before and I find it weird.
FWIW, Arch just updated to Gnome 44 and I suspect that might have something to do with it, but who knows?!
