Photoshop 2020: Temp Files Filling Scratch Disk FAST (possible memory leak?)

I work with extremely large PSB files (~20-100 GB). Supercharged Windows 10 machine built for this purpose alone, that includes:
  • NIVIDIA Quadro P4000 (8 GB RAM)
  • 128 GB RAM
  • 1 TB OS Drive
  • 14 TB Data Drive
  • 4 TB Data Drive
  • 2 TB, RAID 0 scratch disk 
Previous project file was 50 GB and used approximately 500 GB of my scratch disk. Current project file is now reduced to 22 GB. After upgrade to PS 2020, I had to add 2 additional scratch disk options and TEMP files are now eating 4 TB and counting! It's creating anywhere from 3 to 8 new 64 GB Temp files every minute when using the program!

After spending 1 hour on tech support, I was told this is normal, expected behavior; to use 10+ times as much scratch disk space as Photoshop 2019!

Version 21.0.2 should be available to you shortly and contains our changes to correct the excessive scratch space usage issues with Legacy Compositing disabled.

I'd like to know whether the changes have resolved all the issues listed here.  If you still have document size issues with 21.0.2, please follow up by eMailing me at carboni @ adobe . com (no spaces).  I want to make sure we get this right.

Thanks!

I find this issue happens all the time even with PS2019 ... Photoshop does not clean up after itself either, leaving huge gigabyte orphan temp files.

Latest "critical update" does not help this issue, in fact, made matters worse. Now showing 0 bytes for file size but still eating my scratch disk! 14+ TB gone in less than 1 hour. 23 temp files in 1 minute. Can't use key strokes, can't check preferences, can't exit the program! Everything gives EXTREMELY helpful "due to disk error" error message. Yes, Adobe, that IS sarcasm!

Yes, I'm having the exact same issue!!! Dozens of 64GB Temp Files are filling all 7 TB of scratch disk space (in about 30 minutes), and then not allowing me to "save". I switched back to PS 2019 and it's not an issue. I've lost many hours of productivity over this issue! HELP! FAST!

Well, I just found out that if I work on my smart object using clone stamp, within only 5 minutes, my scratch file grew to 250GB !!! After a while, it took 350GB, the whole space on my HDD and I had a problem to save my work...

Something is really wrong as I had no problems in PS2019.

Hi Greg, presuming you haven't already been contacted by and are working with someone from Adobe, I'd like to try to learn more about what you're seeing.

I'm sure you already know that Photoshop keeps an entire copy of your document's working memory content for EACH new step stored in the History panel, and that is expected to grow.  The total scratch disk space used for such history states can be limited by configuring the History States setting in the Performance Preferences panel.

We've tried generally to reproduce the issue you've stated here on several of our big Windows systems but beyond just what you'd expect by multiplying out the storage needed to keep the History states during editing we're not seeing runaway usage of scratch disks.  Presuming what you're reporting goes beyond multiplying width x height x depth x history states, can you describe what operations you're doing to cause an increasing number of scratch files to accumulate?

Thanks!

We are having the same issue on ~2GB files. Temp files of ~60GB are being created in Photoshop 2020 with every change. Mac 10.14.6. Just ridiculous and totally unworkable.

Thank you everyone and especially Phillip and Greg.

We have received a file with which we can reproduce the issue where we are seeing more than 10x additional scratch data stored from Photoshop 2020 than with Photoshop CC 2019.  We're actively looking into it.

Update:

We have identified a workaround that has little downside and should allow you to use Photoshop 2020 for your big projects without blowing out your scratch space:

Go into Preferences > Performance and check the [ ] Legacy Compositing setting, then Quit and restart Photoshop.

Please let me know here if you continue to have any issues with scratch file sizes after doing the above.

Thanks!

I have same issues working non destructive but not many layers. PS says Doc size is - for example - 64.9M/171.3M However once saved it's 454.4M!!! and this is not the temp file!
Since updating to PS 2020 I have worked on 5 files and it has taken up over 15GO of space!
I have reset Preferences but issue remains.
Also filter lighting effects via smart filter NOT WORKING PROPERLY... and even crashing.
I have done the legacy compositing.
Looking forward to your response,
Thanks

hi, I have updated to 21.0.2 as well as Camera raw and Lightroom.
Have opened same file used as test in previous update.
A.: PS crashed - identical - filter lighting effects via smart filter and not working correctly
B.: Original raw file 35.47MB - with xmp lightroom modifications; One action with content aware move ( small part of file ) creating layer and file saved in TIFF becomes 210.7MB!!
C.: Original Raw file - with xmp lightroom modifications > opened on PS and saved (without any modifications) in TIFF becomes 108.5MB
Legacy compositing disabled, PS closed and reopened.
I will email y Noel as there is also an issue with Lightroom classic color luminosity varies from "development module" back to "library module"
Best,
Isa

21.0.2 doesn't seem to be releasing memory when using Edit->Purge->Purge All.

I had an image that was consuming > 16GB of memory.  After  a Purge All very little memory was reclaimed - still over 16GB used. 

I checked Use Legacy Compositing and restarted PS and reloaded same image.  Less than 2GB of memory used.

Looks like this issue is back since the 21.1.2 update yesterday. One Magic Wand application fills up all the scratch disk space. I have plenty though: 250GB left on a 1TB SSD.

Hi Elmar, I'm sorry you're having a problem.  Can you please let us know a little more about your working environment?  Please confirm PC vs. Mac, and let us know some detail on the image you're working with (e.g., pixel dimensions, bit depth, how complex the selection is, etc.).

Unfortunately, I cannot reproduce what you are seeing.  With a number of Magic Wand selections on a big, multilayer 64 megapixel image I'm not seeing the scratch usage grow appreciably.

Lastly - and I hate to parrot this but it helps just often enough that it's worth suggesting - could you please try making note of any custom preferences you have set then resetting your preferences (there's a [Reset Preferences On Quit] button for this in the General preferences panel).  Try the same operation again after restarting Photoshop.

Thanks.
