With v21.1.0 of photoshop, when I use the color picker, memory goes out the roof and the application freezes. Simple to reproduce. I have 2 images, use color picker on one and then select paint brush. That's it. I have to force quit after that. This never happened before now. This mac is brand new and has sufficient horse power (Mojave 10.14.6, 3/6 GHz Intel Core i9, 32 GB DDR4 memory, Radeon Pro 4 GB graphics) and only have a couple of applications installed - so still pretty clean. Oh, and in preferences Photoshop has an 80% memory setting for performance. Any help would be apprecianted.

There was an update/bug fix what? yesterday, the day before? Did you get it? I'm on that and the Color Picker, 2 images, etc. all works fine running the same OS—much older computer with lower specs.

If you're running the very latest PS, x106 (look at the first line of System Info in Help to be sure), then show a screenshot or give us step by step so we have an idea of what might be different.

I guess I have the fix? I do not see any new updates in the Creative Cloud updates list.  v21.1.0 is the latest there. Is there a separate bug fix I need to download/install?

But I did figure out the steps to replicate this. Just using the color picker did not do the trick. Doing the following, however, does indeed make it happen every time:

This test involves 2 psd files, any two. I experimented and size or number of layers does not factor into it. And you have to do these steps exactly:

File #1
1) Have a photoshop file with at least 2 layers open and docked to the main app's layout.
2) Zoom in a couple of times on the file from #1
3) Also in this same file from #1, change something and leave it in the "unsaved" state (i.e. you see the little asterisk)

File #2
4) Open a second file.
5) Zoom in a couple of times on the second file also
6) Move the second file out so that it is un-docked and free floating to the side of the main Photoshop application
7) Take the color picker and sample a color from this second file
8) Click the paint brush icon

I'm not sure if the fact of having zoomed in a couple of times on both files contributes to this or the fact that file #1 is in an unsaved state at the time, or maybe a combination of both?

Regardless, if I follow these steps it puts Photoshop in an unresponsive state.

I've attached a screenshot of the activity monitor, if this helps, to show what happens with the CPU when this happens.

Since File A and File B can be any two files I didn't think you'd need screenshots of that, but let me know if you do and I can screenshot play by play.

Thanks for the help

Okay, this seems directly related to a bug I just found recently. It's not exactly the same—that is, with identical steps. And mine is the eyedropper, not the Color Picker itself. There's no brush tool involved. I can't replicate the problem with your steps—tried twice, but then I went the step further to see what would happen if I used the eyedropper tool—would that cause the PS hang I've experienced — twice earlier today, and a couple of times the day before.  So I selected color with the eyedropper from one—it worked, then the other—it failed and hung PS. 

The other times, I have had the eyedropper selected, and two documents open, only one with multiple layers, both tabbed to the App frame, but arranged vertically. I was using one as a source for the other, and the source was a JPEG, the other a PSD. So slightly different circumstances, but too close to  think they're  not connected.

It's not happened every time I use the eyedropper to select a color, but very, very frequently. I haven't been able to pin exactly what prompts the hang, other than using the eyedropper to sample from one of the two documents. I can sample a few times and then sudden death.

Could you run through this once more, your steps, and when it hangs, check not only PS in the Activity Monitor for Not Responding, but also "dimexe" Not Responding? I don't know what dimexe is, but it's been not responding when PS isn't responding. Ought to mean something to Adobe.

I misspoke earlier. It's actually the eyedropper for me too. I was just incorrectly calling the "color picker". But after reading your reply I realize we're talking about the same feature - the "eyedropper". 

I repeated my steps and Photoshop stops responding, but I did not see "dimexe" anywhere in the list of processes.

Is there some way to open an official bug with Adobe?

I just installed on older version (v20.0.8) and it does not hang when using the eyedropper. So I guess for now I'll use this version since I can continue my workflow without constantly having to restart. I guess there's an eyedropper bug in the latest version. I'll stay on this version until another version is release to see if it gets fixed.

"Problem" is a bug report. Adobe Staff monitor this site and with a confirmed bug like this, they'll add it to their list. Yes, I didn't experience it until recently either, so going backwards is the way around it. Good to have my own suspicions verified that it wasn't my computer acting up. With an older computer, I never feel absolutely certain that gremlins haven't taken up residence. <g>

Interesting that I have this dimexe and you don't. Oh well. It may be nothing there, then.

This reply was created from a merged topic originally titled Photoshop 21.1.0 mac. eyedropper tool hangs photoshop when sampling from second w....

hi, Photoshop 21.1.0 mac. eyedropper tool hangs photoshop when sampling from second window 100% repeatable. (tho doesn't hang if using application frame, only floating windows) have to force quit so it's not triggering the bug reporter.  version 21.0.3 works fine. tried switching off gpu acceleration with no luck.

edit/ hang doesn't occur if the window is given focus first, only if it's sampled without bringing to front

This should be fixed in 21.1.1 or later. Let us know if you're still having trouble.
