P: Lagging while zooming and painting with Native Canvas Rulers enabled - PS (v23.2.0) Windows

[Robbie Khan]

HI,

Bit of a strange one and I've only noticed this since recent updates. When I have an image (regardless of resolution etc) open and the PS window is active/in-focus, I can zoom in and out with the mouse wheel smoothly as long as the image is fully visible in the PS window canvas. But if I zoom in closer so parts of the image fall outside of the canvas, then zooming is laggy, like as if there's a CPU spike laggy but there actually is not any CPU spike.

If I click out of the PS window so PS is no longer in-focus, and then hover the mouse over the PS window and then zoom (WIndows by default will allow scrolling or zooming on whatever window app window the mouse is hovered over) then the exact same zooming actions are smooth.

I have recorded a video showing what i mean to help give a better visual of what I'm on about: https://youtu.be/3Xv7E-JPnZg

My mouse is a Logitech MX Master 3 and it is running the latest software, this issue has only been noticed since recent PS updates though so I don't think it is mouse related. Zooming using CTRL & -/+ on the keyboard does not exhibit this issue however, but the zooming steps are much larger using the keyboard shortcut.

I am on Windows 11 (up to date) and have the nVidia Studio driver v511.65.

Cheers!

Setting sprk to 200 didn't fix the problem, but disabling the ruler technology preview as you suggested seems to work!

[Dimirti2228157372hc]

Disabling "Enable Native Canvas Rulers" in Edit>Preferences>Developer preview seems to help.

Hi everybody.

23.2.1 installed a few days ago and I've purposely left it a short while to see if things straighten themselves out but that doesn't seem to have happened. I am also unsure as to the full extent of tools that are affected but I notice this particularly with the Zoom tool....

The screen is not very responsive at all and the mouse pointer jerks about as if a lot of buffering is going on. The problem of lag manifests in such a way that memory is low or the PC is struggling to keep up. That is if I using Alt + Mousewheel. Clicking + / - Zoom at the top works normally and as it should.

It's really bad, everything slows down to almost a griding stop but only since the new 23.2.1.

I just wondered if anybody else was having simialr difficulties?

[Ged_Traynor]

Hi

Do you have the rulers enabled when you noticed the lag, if so try disabling this option in preferences and restarting Photoshop to see if it helps

[J453]

Go to Preferences > Technology Previews... and disable "Enable Native Canvas Rulers" and restart Photoshop, does it work better?

[Theskichick]

Hi @Ged_Traynor I do use rulers but don't generally have them enabled. Most usually, and now, they are off. Thanks for the idea though, I do appreciate it.

[J453]

@Theskichick Did disabling "Enable Native Clanvas Rulers" help? (And just to confirm, you restarted Photoshop after clicking this option?)

[adrianl91021716]

I had this issue too but with all the other tools. My healing brush would delay the ALT key by about 2 seconds each time on and off. This was driving me insane.

Adobe, QA needs to step it up. This is professional production software not a hobbyist kit!

[Paul Waijman]

Same problem witht the latest 2.3.2.1 update as well. 

Turning off rulers fixes the issue. 

Hopefully Adobe gets on top of fixing that so we can use rulers and Wacom hardware (in my case, Cintiq display).

[victorwisy]

I had the same issue.. Mouse lag after pressing ALT.

Solved after Disabling " Enable native canvas ruler"

Thanks Jeffrey

[Reveraine]

I am having the same issue with both 23.2 and 23.2.1 , I need to use rulers, so I have reverted to 23.1.1 until this is fixed.

[Reveraine]

If you have the ability to switch, 23.1.1 still seems to work properly with rulers. (In case you didn't know, you can reinstall older versions using the (...) next to open in creative cloud and go to (Other Versions). 

[Paul Waijman]

I had been doing that up until today. Thanks for the other workaround. 

[GZK666]

Better, but still not the same speed as before

[RahulS.]

Hi,

I am using Photoshop 2022 (23.2.1). When I used the mouse scroll wheel to zoom in and out of the layer, it slows down and zoom in-out bit by bit, not smoothly.

Thanks 🙂

Hy every one !  
I have a bug in toshop. when i draw, sometimes it's delaying (Exemple under) sorry for my english.
Thank you for your answers

Things to try:
Preferences > Technical Previews:
disable: Enable Content Credentials (Beta)
disable: Enable Native Canvas Rulers
enable: Deactivate Native Canvas
restart Photoshop and let me know if that solves the paint stroke delay.  Also try with Rulers on/off (Ctrl+R).

I am having the same issue. The issue became present in version 23.0. Version 22.5.6 does not lag when using the scroll wheel for zoom, so you can go back to that older version to avoid the issue for now.

My guess is there is a redraw issue at certain zoom percentages. If you zoom with a mouse click you get easily divided pecentages 12.5%,25%, etc. with no lag but when you use a scroll wheel it's scrolls in odd percentages such as 36.7%, 46.8% etc. and that is where you'll see the most lag. Using the zoom tool and click and dragging seems to not lag at all and is very smooth, but having to switch to the zoom tool constantly is not ideal for most work.

For any of the developers reading this, the reason why we use the scroll wheel zoom vs using the zoom tool is because we  need to zoom without changing the tool we are currently using. It is beneficial for us to be able to zoom in and out quickly without switching tools making the lag we are experiencing with the scroll wheel extremely frustrating to deal with. 

[J453]

If you go to Preferences > Technology Previews... and uncheck "Enable Native Canvas Rulers" and restart Photoshop, does the problem persist?

[Digital Halftones]

Jeff,

That seems to have worked, so it's an issue with GPU acceleration. The odd thing is I tried turning off "use graphics processor" first to test if it was GPU related, but this "native canvas rulers" seemed to keep GPU acceleration on regardless. I have an AMD 6900xt graphics card if that helps pin down what is causing it to lag. 

Thank you for the fix. After a few weeks of dealing with the lag it was really starting to get to me. 

[maximel66031936]

It works ! Thanks a lot 😄 

[Dylan5C43]

Also had this problem with v23.2.1 - Disabling the rulers helped, Thanks! (Just frustrating for when you need rulers or guides) What is the reccomended version rollback to avoid this issue?
