Photos Greyed out in Develop Module Lightroom Classic February 10th 2022

[John1957]

Photos are greyed out in the DEVELOP module, it happens when I adjust the Luminance slider in the Detail section. After putting the slider back to zero some photos return to normal, some remain greyed out. Anyone else have this? Have I missed something?

First, try disabling GPU in the preferences (Preformance tab). Any better?
If not, recalibrate and build a new ICC display profile, the old one might be corrupted.
If you are using software/hardware for this task, be sure the software is set to build a matrix not LUT profile, Version 2 not Version 4 profile.
If turning OFF GPU works, it's a GPU bug and you need to contact the manufacturer or find out if there's an updated driver for it.

Thanks, turning off the GPU appears to have done the trick.
