Description

Main histogram changes when a different display profile is selected. Appended images all taken from development of same raw image, only difference is display profile (selected through monitor icon in lower right of darkroom).
Expected: histogram should reflect values in image according to history (or step in history that is currently selected).
Could be related to bug #9194 (global color picker depends on display profile).
Darktable 2.6.0 ("Affected version" below does not allow selecting above 2.4.4) on Archlinux 4.20.5-arch1-1-ARCH.

Agreed. Same with the globad color picker.

But it has other implications such as making the whole pipe independant from the output profile.
