Applying ICC profile in Wayland Plasma results in heavy artifacts

Hey all,

I rented a SpyderX from a local rental to calibrate my laptop screen and external screens.
I measured and profiled for a 6500K color temperature at 200cd/m² at Gamma 2.2.
After measuring all three screens, two identical external screens and the built in one, I tried applying the created ICC profile
in Plasma's System Settings under Display Configuration, but it results in heavy artifacts on the screen.

Under XOrg, applying through color management works fine for the built in display. The external displays
don't work under X because I'm using an eGPU (a GTX1060) setup which only works properly under Wayland.

Under X it uses the laptop's GPU, a Quadro P1000 which uses the same drivers, so there shouldn't be any differences there,
though only the embedded display works then.

Running linux 6.19.9-arch1-1 with Nvidia drivers 580.142 (the nvidia-580xx-dkms package).

Picture of two screens, the bottom one has the ICC profile applied (both should be same brightness):

All screens show the same type of artifact when their ICC profile is applied to them

I should note, under X11 with the working ICC profile applied, Darktable distorts images in a similar way when
"System display profile" or the imported ICC is selected for the display profile. Choosing anything else
works fine.

You have tried with the manual method described at https://wiki.archlinux.org/title/ICC_profiles#Wayland ?

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

For clarity :
you copied (using root rights) your icc profile to /usr/share/color/icc/colord/ ?
after that you rebooted to ensure wayland / colormgr will detect the new file ?

Hate to say it, but it started working overnight. Now applying ICC profiles through Display Configuration in System Settings works as expected.
