Since Ps 23.x most adjustment layers, unfortunately specially Curves, are super slow, throtteled and jerky. - Please fix that asap, thanks.

MacOS Monterey 12.0.1

Appreciate any feedback. Specially if ther is a workaround to fix this prior to bug fix.

(The Disable Native Canvas thing is weird - as according to the Known Issues, that's a GSync bug but I'm on non-GSync monitors.)

@J453I installed 23.2, there is no change in the behaviour of Photoshop when zoom is used, can we agree your team was not able to reproduce this bug yet? my point is maybe I should prepare video now...

No improvement here too. The Curves are maybe slightly more responsive when used as an adjustment layer or direct on pixel layer. But adjusting Masks is still painfully slow. Here is a video showing the issue: https://youtu.be/ihJthBXe0tw

It is quite responsive when zoomed out, but when zoomed in very close (the way I need it to be to make adjustments) is not usable. See for yourself in the video.

 

Please look into it closer. The issue is not resolved.

 

Thanks!

@laden.mexactly same behaviour as I have on my computer for more than a year with new Photoshop, I think the reason they are not able to reproduce it is because they use different configurations, however, could you check what will happen if you open empty image, let's say 4000x3000 and try to do same test? on my computer the bug is not visible, that's the reason I think some special conditions must be met (I always open photo from Lightroom, which is never "empty")

@Jacek Poplawski My test image was 12000x8000 pixels and with approx. 60 Layers, but still I want to adjust just one flat grayscale mask. Why should the layers play any role here? It is just not normal. It has to be much slower when dealing with the adjustment layer on top of all layers because it needs to calculate all the data below?

 

I just tried with one 3000x3000 pixel single layer image and it is much faster obviously, but still slower when zoomed in.

@tiadencould you describe simple procedure how to create good test case from scratch, I mean open Photoshop, open empty image and then do what to have state when bug happens? I tried that and it is not so easy, it's not really about number of layers because I see this bug on my photos with few layers (curves, color balance, selective colors plus dnb masks)

The problem still persists for me as well. PSB with about 250 layers and a curve on top. Zoomed out it is ok, but zoomed in it's nearly unusable. Document dimensions are about 14000 x 1200 px.
Disabling native canvas improves the curve behaviour not being that sticky, but the overall performance stays poor, for example slow brush strokes. Performace is good when fully zoomed out.

I still use PS CC2018 for everyday work.

@Marek Domkecan you tell me how to use CC 2018? I was using old version of PS but this evil corporation removed it after some update and I had new version only, without any way to revert it back

Some more videos of the same thing (I think). Showing back when it used to be fine and nowish):

 

Perfectly smooth in v21.0.3, horrible laggy on everything in v21, v22 and v23 since that release:

@Mohit Goyalplease don't tag is as correct answer because your change doesn't fix anything, as discussed previously with @J453 I believe you were not able to reproduce issue yet, this issue exist in PS for more than year (maybe almost two years now?) and if the issue was not reproduced at all in Adobe it means you have some different configurations, maybe only very powerful computers? or maybe it is related to amount of memory (I was testing it but memory usage by PS doesn't increase, but maybe PS uses some heurestics to slow down when available memory is too small), please try to reproduce the issue in Adobe, please look at attached videos

@Jacek Poplawski I don't know what could be more powerful on average base compared to my Mac Pro (2019) with 3.3 GHz 12 Core Xeon and 192GB RAM, 16GB RadeonPro W5700X. And it is still super slow,  actually slower than on my previous Mac Pro and previous PS Versions.

If Adobe can't reproduce it, they must have some crazy fast rigs there:)

@laden.mok if you are on 192GB computer then we can safely say it's not related to memory size of computer 🙂

v23.2 on an M1 and this issue still is NOT resolved. Adobe, you need to test when viewed at 100% or when in mask view.

@Earth OliverI am not sure are we talking about same thing, it's not that Photoshop is slow it's that Photoshop is unusable, you can't do dodge and burn correctly, I don't remember any youtube video or for example proedu video with non functional dodge and burn or curves

@Jacek Poplawski I think because they are using not so large files and only with a few layers. With smaller files and just 2-8 Layers, everything works fine here. It is still not super responsive, but not an issue. 

My problem is that most of my files are huge and with many many layers. But wasn't Photoshop built exactly for that?
