I am been using IMAC 27 inch 5K late 2015 model and I am been observing a very awkward issue with my lightroom classic. It seems to hang and then freezes my entire system forcing me to shut down my computer via the power button.

The glitch only seems to occur when working on LRC.

Can anyone help me how to fix the issue?

thanks in advance

Hi!

I've spent about 2hours with Adobe support on remote desktop to solve this exact same issue. They totally DO NOT know that to do about it, or should I say, they don't know anything . Guy on support tried to persuade me that my network drive are what causes this problem! Asked me the same questions for at least five times. I'm totally pissed of!

Lightroom Classic 10.1 has a massive problem with GPU memory leak! Once the vido memory is more than 95% full, LcR overflows it and freezes whole system, makes it totally unusable for tens of seconds. Sometimes minutes.

The fix is quite easy, downgrade back to LrC 10.0 or disable GPU acceleration in 10.1.

This bug causes my whole system to freeze, show artifacts on screen, display green frames in video or disables video playback in macOS Big Sur 11.1 totally. Until I restart my iMac.

Same problem all day long, but not on BigSur and on a normal MacPro. Everything was fine until yesterday. Very annoying indeed and makes it impossible to deliver a job due...

I have got nearly the same problem on the same platform (brand new iMac 27" 5K 2020 / Catalina 10.15.7+ Eizo 2731 and

AMD Radeon Pro 5500 XT 8 Go).

Lightroom Classic 10.1

Images out of a Canon 5DMK4 (RAW).

My machine is going very slow after only 10 minutes of usage (even with 24Gb main memory) , often freeze, the red mask of the brush sometime do not appear...then brutal crash of the machine happened several time since upgrade to this version.

Desinstalled and reinstalled Lightroom....same situation.

Working with Photoshop has NONE of this problems...

Huge impact on my work ....

Firstly I thought that it is problem only presen on Big Sur 11.1 but it's not.

I suggest to pay attention to your GPU's memory load. My system i iMac 27" 5K late 2015.

Once GPU memory si loaded for more than 90-95% this problem seems to rise.

Because of 5K screens there computers have GPU memory fully loaded almost all the time. Notoriously LrC had problems with GPU memory in past. There has been a bug (a year ago aprox.) that caused loading GPU memory contents into exported photos. Resulting in Safari websites content baked into exported JPGs and some other "funny" artifats.

Adobe, fix your products! Number of bugs especially in LR/LrC/PS is inacceptable! Not mentioning PS2021 memory leaks :-/.

I did not install Big Sur to avoid problems... ;-).......but problems are there anyway...

I tried to disable GPU acceleration last week with no success...same problems...

Re install of last version of LRc ended the same way...

I confirm high usage of GPU memory : 95% (the graphic proc, only 2% ) => iStats numbers...

Like you I understand that the 5K display is a real pain to display , and in my config I also have a secondary display 27" EIZO (Graphic Arts screen) to run...

My previous machine (2 weeks ago) was a 27" 2015 and was running LRC very fine.... I changed it because I wanted to be able to work more quickly.... (what a strange idea...)

Will try to install "version -1"....we will see...

I have no problems with PS....that point seems different from you...
