I just recently updated to Adobe Photoshop CC 2019, and my healing brush tools and clone stamp tool lags when I use it.  I had no prior issues with CC 2018.  What gives?

Same problem here. Clone stamp performance is horrible and it seems that they changed the algorithm behind it. Doesn't work that flawless anymore. :(

@Adam, your solution doesn't work either.

Try to hide the ruler. It should help a bit.

Yeah, strange but true. The lag is terrible but almost goes away completely once the rulers are hidden.

This reply was created from a merged topic originally titled Update to Mojave brings Spinning Wait Cursor while painting with brush..

1. Update to Mojave
2. Updated Photoshop
3. Started painting with the brush tool on a simple file with layers
4. The cursor icon switches to the Spinning Wait Cursor while painting for about
5 seconds
6. Happens with both my wacom pen and mouse
7. The brush tool is not lagging when this wait cursor appears.It's annoying and I don't recall this happing ever before the OSX update.All drivers and software is up to date.

This reply was created from a merged topic originally titled Photoshop CC2019: Brush busy cursor and lag when rulers are visible.

Hey guys, after updating to PS CC2019 I'm having a ton of issues with the brush tool, I've cross posted this from twitter and other adobe forums in the interest of clearer bug reporting and visibility.





iMac (Retina 5K, 27-inch, Late 2014)
macOS Mojave 10.14
4 GHz Intel Core i7
32 GB 1600 MHz DDR3
AMD Radeon R9 M295X 4096 MB
Wacom Cintiq 27QHD

These all seem to be linked to Mojave specifically and only occur when rulers are visible. If they are hidden they do not occur. I have attempted a number of regular performance fixes that adobe customer support suggested on twitter as well as different forums, this includes things like purging preferences, re-installation, turning off GPU use and turning on legacy compositing. From what I've gathered from other users, with most people experiencing this issue the common links are, PS CC2019, Mojave, Ruler visibility and a Wacom product.

The reproducible bugs are:

1: If I hold a brushstroke for any more than a second or two (with rulers visible) I get a busy cursor (a ring of rotating dots) this happens no matter if Im using my mouse or the wacom. It no longer allows me to see the brush tip shape but will continue to make the brush stroke just fine. This happens no matter how small the document or how simple the brush.

2: After I make multiple consecutive brush strokes photoshop cant seem to quite keep up, if I make 5 brush strokes in rapid succession the first one may appear in real time but they rapidly begin to fall behind where my cursor actually is. This does not happen in cc2018 where i'm using the exact same brush on the same document size. These are simple round brushes on small documents, I'm really not pushing it. (This may have improved with a preference reset its hard to tell)


3: It seems to occasionally (every 10th input or so) skip a brushstroke, making only a single low opacity circle or no mark at all without drawing the rest of the line. I can scrub the cursor across the document at full pressure and it makes no mark till I lift the pen off the tablet to make a new mark.


To clarify these issues only seem to occur when rulers are visible, all though I will still very rarely get a busy cursor when painting with them hidden all though that seems unrelated.

Heres a video showing at least the busy cursor bug: https://youtu.be/cSet4UQiitw
The other bugs are too inconsistent to easily show but seem related to the issue since they all occur under the same conditions.

"I will still very rarely get a busy cursor when painting with them hidden"

i think this might have to do with technique a little. something about the way i draw seems to trigger the busy cursor constantly, even with rulers disabled

Instead of posting unlikely workarounds and/or suggestion, when Adobe is going to fix those RIDICULOUS issues?
We are not talking about issues affecting some improbable combination of operations...
We are talking about bugs on tools used EVERY SECONDS from photoshoppers.
How could a product su buggy pass the QA test?
I'm shocked as photoshop user since 1993 !!!!
Best regards!

Mine isn't lag but a big red dot where I Alt to select. Then nothing happens except when I move my cursor.  Then the red dot gets bigger or smaller depending on where I move my cursor. And when it actually does make a selection I get a pop up brush box that is right in the middle of where I need to work.  This is costing me precious time.  My clone stamp tool used to work beautifully.

What you describe sounds like Photoshop thinks another modifier key is down (so it's showing the brush size hud). Are you using a tablet? Sounds like the shortcuts pref is whack in there.

Thanks for the quick response.  Yes I am using a tablet but it does the same thing when i hold the Alt key on the keyboard.  And the pop up Brush box is infuriating.  If I put my pen nib down on the tablet I get a white circle then a pop up list. I'm wondering if my mouse setting in windows have something to do with it.

Possibly. Double-Click speed set too fast?

I changed settings in Wacom, Logitech and Windows.  We will have to see what happens next
Thanks again for your help.

After applying the 20.0.1 update, you will need to do the following for macOS 10.14.1:

Run the following command from the Terminal:
defaults write -g PhotoshopForceLegacyPaintMode -bool Yes
Then you have to enable Photoshop in System Preferences > Security > Accessibility

Possibly. There's an unexpected interaction with Mojave. We're working with Apple on a longer term solution. May be a PS change, might be an OS change. TBD.

When Adobe finally resolves the issue, then what? Does the DEFAULTS edit need to be undone somehow? And if so, how?

We'll update the tech doc if any changes are necessary: Pen pressure does not work and busy cursor displays while painting
