Subject: issue when applying ICC profile to display after drm/i915 change

Hello,

this used to work.

xcalib D6200MTX.icc


After this it stopped working

commit 20a34e78f0d71cab058a943b2e9601b97b761227
drm/i915: Update color management during vblank evasion.


Color profile only take effect after the screen if back on.

xcalib D6200MTX.icc
xrandr --output eDP1 --off
xrandr --output eDP1 --auto


thanks
