P: Desktop Memory leak on M1 Machines

@Rikk

No, it doesn't.

Please trust me Rikk! Memory leak is a real issue on Lightroom M1. These users also encounter same problem:

This is actually a massive issue.  There is no way this isn't wide spread on M1 mac's.  I have 3 M1 mac's and they all do the exact same thing, this does NOT happen on my intel iMac.  As soon as you double click a photo the app goes from around 1GB of RAM used to 6-8GB without doing anything else.  It never releases the RAM until you close the app.  This basically makes the app completely unusable.  It's kind of insane this is even happening.

After exporting the photo and waiting 10 minutes or so without doing additional work in Lightroom, does it return the memory?

Hi @Rikk

So sorry for the late reply.

I performed the 9 steps as you have instructed (evidences: https://drive.google.com/file/d/1nRQiMjt__RpOuOshLRBdEe_hBYbujAfR/view?usp=sharing)

However, the problem persists. In particular:

- the app consumes 5 GB of memory when I double click on a photo (video:16:24)

- the app (Lightroom Helpers) consumes 5 extra GB of memory when I click export (video:17:08)

So in total, the app consumes 10 GB of memory when exporting a photo.

Please help!

This tells me you've done a preference reset but not a clean install.

Hi Rick!

Have you performed a clean install? A preference file reset?

Oh yes. Last week, I reported an issue with export (https://feedback.photoshop.com/conversations/lightroom-desktop-cloudbased/lightroom-desktop-cloud-based-stuck-on-preparing-for-export/6085848aa8e98c342a79e6e9). You suggested me to do a preference file reset. However, the problem (fail to export) resurfaced after a few days. A detailed investigation reveals that export failure is due to memory leak.

I have then performed a clean install ("Use the Adobe Creative Cloud App to uninstall Lightroom") and "Restart the computer". The problem, however, persisted (attached photo) 

=> To sum up, I have both performed clean install + preference file reset

This is not a commonly reported issue. 

This can be explained. Mac M1 has just released recently. Therefore very few users use Lightroom CC on Apple Silicon.

This is not a commonly reported issue.
