Hi @Duc Ha Minh A34504867qpb1 

Hope you are doing well and thanks for reaching out.

Is this an issue with a particular PDF file or with all the PDFs? Please try with a different PDF file and check.

Make sure you have the application updated to the recent version 23.08.2042X from the help menu > Check for updates and reboot the computer once.

Also, go to Preferences (Cmd+K) > Page display > Under Rendering, Uncheck 'Use page cache' > Click OK and reboot the application once and check.

Even with unchecking 'Use Page Cashe', I'm getting a very stuttery block-like pattern as Acrobat very slowly attempts to render and re-render each block, while zooming. This behavior appears when working with large (80MB) single page images. Acrobat ultimately completes the task, but it takes five minutes + before gaining stability for zooms beyond 200%. It goes through the same behavior when scrolling a zoomed image, too. The image is a PDF, not a jpeg.

I'm on a 4-core iMac with 32GB of memory. I'm posting a movie of the behavior. I don't see this kind of behavior on my laptop This is using Acrobat version 2023.008.20470.

Just updated to 20533 and this issue seems to have largely gone away. Thank you! Still pauses and flickers a bit when zooming in really close.

This is not solved. I have the latest update. It still will not display any large format files properly. Just refreshes a bunch of squares over and over. I have a 10ft x 6ft banner that will not zoom in or view at 100% to check for any issues. I've been working with files like this for over 20 years. This is absurd.

On a positive note, to my graphic artist friends trying to deal with this. I don't know if it is useful for anyone but Apple's Preview app opens the same files and will view at 100% in a few seconds!!!

This is labelled as correct answer??? By whom? I am on 2024.002.20893 and still can't zoom past 25% on a 5MB file without Adobe Acrobat Pro freaking out. It's not the solution - Adobe please do better!

[Sheridan36591906zea5]

Acrobat Pro has all these new whizz-bang features and yet it can't even do basic zoom.

[egonb5088883]

I am now on version 2024.001.20604 and here too I am experiencing poor zooming in on certain files, especially for certain customers. Sometimes I let Acrobat Pro do its thing and it can run forever and not generate an image! And forever I mean forever! My Mac even goes into sleep mode in the meantime!

It looks like a gnome scrolls every time the image is almost finished! But I joke about it now, but it is horrible to work with this every day as a Professional!

And whether it is Acrobat Pro or the way the customer exports his PDF files, I really have no idea! But I don't have any problems with my own PDF files!

Hi there

Is this an issue with a particular PDF file or all the PDFs? Please try with a different file and check.

If its a specific PDF file issue, please share the the PDF in question and a small video recording of the steps you are doing so we can try to replicate the issue at our end and check further.

Also, make sure you have the recent version 24.01.20615 installed. Go to Help > Check for updates and reboot the computer once.

I have indicated that it happens most often with PDF files from certain customers, but I cannot quickly figure out WHAT they may be doing wrong when exporting their PDF files! Probably something with an overlay, clipping mask, ancor points or transparency.

I don't have any problems with PDF files that I export myself! But you I have been exporting PDF files for 25 years!

[Amal.]

Hi there, we are glad to hear that the application is working fine for you.  Would it be possible to ask the customer to share a sample PDF file for checking? Also, ask them to be on the updated version of the application.

I have the same issue as some of the other users, have done ever since I updated to the latest vs of acrobat. Never had any problems before but it now makes acrobat nearly unusable.  I tried reinstalling, turning off the security settings but neither worked.  The lack of scroll bars is also a total headache.  Doubly so with the extraordinarily slow refresh.  Any help appreciated.  I currently have to resort to using apple preview (which is not great) or printing and marking things up by hand.  Tedious

[egonb5088883]

Received another notification and see that the problem still exists and therefore also affects other users! I think Adobe is thinking too lightly about this and this has actually made Acrobat for Professionals almost unusable! I made a screenshot of what happens every day when I use Acrobat Pro and this is no exception!

You see a file provided by a customer. The file is large 1400x2000mm but as you can see in one of the screen shots, it is just a pixelated image of 108ppi. You would expect the background to be a vector image, but it is not!

I hope that Acrobat finally takes this seriously.

This is a nightmare for print production and checking proofs!!!! It has improved with updates less flickering but it is definitely not fixed. Print production you need to be able to zoom in to check and this mindnumbingly slow refresh is costing me time which is money.

[lululinda]

I may have just found something useful for print production and proofing/zooming. I have turned OFF the following in Preferences > Rendering: Smooth line art, Smooth images, Enhance think lines and Use page cache. Now I can zoom and see what (I think) is the actual pixels. Please comment if this is working for you and this does what it appears to be doing - showing what will actually print!!

[lululinda]

NOPE, large format display graphics not refreshing. SLOW and useless. 

[johnr10454453]

I got the same result (NOPE). Up until your post, I had all the four options OFF, except enhance thick lines, so I turned that off, too. Then tried to open a 348MB, single-page PDF graphic, to no avail upon zooming in. All kinds of tiles flashing on and off and the image never quite fully rendered. I think there is still a problem, San Jose!

[egonb5088883]

They probably won't admit it, but Adobe Acrobat has become unusable for Large Printing! Where it is often the case is that the customer no longer has the knowledge to supply PDFs for printing!

But sometimes I also have the feeling that the knowledge at Adobe is also slowly disappearing! Acrobat Pro is actually only usable when Enfocus Pitstop Plugin is installed, so I don't have to check everything visually!

But I think I've already tried all of this @lululinda , but I'll check again!

[Sheridan36591906zea5]

Hello Amal and Adobe team - this issue continues. I read so many posts here about people having this problem. I'm having it too and it drives me crazy - so time consuming. It doesn't matter if it's pdfs I make or pdfs from my graphic designer the zoom function is unusable past 25% and these are file that are only 5MB! I am now on Adobe Pro 2024.002.20893 and issue still happens.  Is Adobe planning to do anything about this in next update?

[Alyssa38642445etdc]

I am so relieved to find this thread, because I have struggled with this since updating Acrobat.  It's basically unsuable for viewing large PDFs.  I find even zooming in to 75% of a 24x36 pdf means that I will never be able to see it, it is just a flashing mess of trying to render.  This was all part of my standard workflow previously, so I don't think it's how we are producing pdfs in the office, because that hasn't changed.  I will try some of the things listed, but it doesn't seem to be the solution.

[stolon38370425xw40]

I have recently spoken with a colleague who has reported the same issue, and since the latest update.  Adobe - are you listening? Your customers are feeling very unhappy about this latest version of Acrobat.  Please fix acrobat ASAP.

[egonb5088883]

Welcome to this discussion! I also think that it really has to be Acrobat and not the PDFs we work with! But I suspect that Adobe has shifted their interest to AI lately and has actually neglected Acrobat's most important function, which is PDF viewing, checking, and editing. I also played with those AI functions and when you see how complex the results are, I look forward to future PDFs with fear an dread!

[MGDboston]

I am afraid to say this out loud but ...

This acrobat version is horrible for zooming up.

Everything you commented on was exactly true for me as well.

I would WELCOME back an older version of acrobat pro that does not FAIL

at the most important function of close zooming to check our files.

Anyone know how to get an older version and use it without issue?

[egonb5088883]

As long as customers keep supplying PDF files of over 600MB you will just keep this! The problem is that nobody cares anymore, all Web to Print accept any file, you can send up to 2GB files for free, Adobe has to keep up with other developers, and you simply have to deal with many self-taught Graphic designers. Here is a good example of how customers deliver a PDF and when I am done with it and the PDF is ready for production! Saves 660MB!!! We should reintroduce the ZIP Disks as mandatory delivery media.
