Profile browser loads quickly for unedited images and slowly for already edited ones (video)

[bajanstefan18]

I have amassed a lot of color profile, I'm aware. However, when opening the profile browser while viewing an image that's already been edited, it takes upwards of 10 seconds, as opposed to be instant with unedited images. This is with graphic acceleration enabled and my machine is far from outdated or sluggish in any other respect.

MACOS Big Sur?

Beta user?

[bajanstefan18]

Correct, running Big Sur goldenmaster. I can confirm this behavior has been occurring for the last four beta releases and incrementally becoming worse with each one. Last night I experimented with removing all of my user added profiles and only leaving the default ones in and LrC exhibited the same behavior.

You should probably post at the official Adobe feedback site where actual Adobe techs respond:

And as a Apple beta member, do you have a Apple site to post problems?

[bajanstefan18]

Just posted it over there, appreciate the heads up. And yes, I reported it last night throught the Beta channel feedback app along with the screen recording.

[GoldingD]

This one?
