Lightroom Classic: 10.1 thumbnails erratic behavior with Big Sur

@todd_shaner_6660895  I think it is because a friend just told me that she didn't have any troubles when she was using Catalina, but after the Big Sur upgrade she noticed this strange behavior, another friend using Catalina told me that she haven't seen this issue with 10.1.

Definitely, the Adobe team should take a look at this for a future (hopefully very soon) fix, because it really screws the workflow in some way.  Until then I'm going to keep using 9.4 until the fix comes.

@colin_judge  Yes, the Library Module is awful and totally useless.. but it also happens with the Develop Module, check out this video that I recorded and see how images 12 and 13 just changed their color to a "flat color" once are not selected..   Same as you, I test turning the GPU acceleration off, creating 1:1 previews.. creating new catalogs, etc..  nothing solved the issue.

Strangely, that doesn't happen for me. Very odd.

Thank you both for confirming my frustrations. I currently selling my Mac to solve this issue because it is taking so long for Adobe to address this very obvious and unprofessional problem. Big Sur with current version of LR 10.1.1 is not working properly and I have too many v10 galleries to downgrade to LR 9.4.

Somebody said that if you choose to work with process version 4 instead of the 5 (current) the problem goes away... I havent try it, i just went back to 9.4 until they fix this BIG issue.

@Rikk Still occurring with Big Sur 11.2 and Lightroom Classic 10.1.1

@Rikk I am still experiencing the issue even with the update to the OS.

Mmmm i can confirm too that the problem it's still there with the latest versions of Big Sur and LR

Thanks for checking. 

@Rikk I'm experiencing this same issue with Big Sur 11.2 and LR 10.1.1! Do you have any updates on when Adobe might correct this issue? 

@Rikk just touching base to see if Adobe has addressed this issue yet or has any updates? 

I think it's about time to have a status of this, im stock with the 9.4 version until this issue is fixed =/ =/ 

I am also experiencing this, definitely a huge workflow killer and needs to be fixed very quickly. I am on the most recent Big Sure update 11.2.1 & Lightroom 10.1.1. 

I tried the power off steps as above. How do you change the process version or downgrade a catalogue?

@DMartin  you can't downgrade a catalog once it is upgraded to v10, the process version can be changed under Develop mode, go all the way to the botton and there you will see the vesion you are currently working..  I honestly don't know if changing the version fix the issue, but if you try it and it works, please let us know.   I just downgrade my LR version to 9.4 to avoid any problems until this is fix.

Thanks, I figured that might be the case for the catalogue, that is definitely annoying. Our outsourcing partner is using the new catalogues so I don't even think that is an option for me.

I also can't see that fixing the issue, because then I would also be losing the performance issues they fixed to even work with the M1 Macs so I don't even think I would entertain that option.

Yeah I had a brain fart :) I ended up realizing what the process version was but this did not change anything. Thanks.

Really hope there is something coming soon after two months this being posted. Jobs are starting to happen and I need to be able to check consistency on my images.

@DMartin  totally get the point, Im also starting to get work and im stock with an old version of LR just becase this issue isn't fix, not a good thing at all.

@Roberto506

I did read somewhere that someone created a boot drive of an older OS, which maybe I will try for Catalina. It sucks to think about needing to boot off another hard drive just to use lightroom but I will have to test it out and see what happens. I think from what I have gathered Catalina had no issues with the grid previews, just hopeful I can actually do that on an M1 chip.

Darn quick google search just said that it won't even support older OS, I guess I am going to need to edit on the Wife's laptop until they fix this :/
