Strange Black Boxes on my images - Lightroom Classic 9.4

[Fotodude81]

Hi All,

I'm trying to understand and fix an issue I am seeing when retouching my images using Lightroom Classic. Im seeing black squares show up in place of adjustment nodes. These back squares come and go, and are present on previews when disconnected from the raw files. When raw files are connected back up I can rebuilt the previews and the black boxes go away. Additionaly when previews are exported these boxes are also presents in the exported file. Im running Lightroom Classic 9.4 on MacBook Pro 2016. Anyone have similar issues, whats going on here?

First, try disabling GPU in the preferences (Preformance). Any better?
If not, recalibrate and build a new ICC 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.

Thanks for the tips! Disabling the GPU plus building new preview profiles worked
