INcredibly laggy scroling experience

Adobe Acrobat 64 bit 26.001.21691 is incredibly laggy when scrolling up and down the document.
This is on an R7-7700X and 4080S, It seems to have started about a week ago, scrolling was buttery smooth until then.
No updates that I know of except for Acrobat, checked to be on the latest version.
Everything else I try to open the PDF files with (browser, acrobat web version, NitroPDF and Foxit Reader) seems to have no problems scrolling the documents.

Disabling New Acrobat Reader also restores performance but I like the UI of the new one more if possible.
I’ve tried a restart, repair, reinstallation, uninstall + cleaner for a clean install and the same happens.
Other things that have been tried to no success: Unchecking all combinations of checkboxes under Page Display > Rendering, switching hardware acceleration off and back on, switching rendering from DX9 to software.

Anyone have any idea what else can be done here to restore scrolling capabilities?
This does not happen in reading mode (ctrl + H) even in the new one.

I’m having the exact same issue, exactly as pictured in the video shared.

It happens in regular, non-form pdfs

There isn’t a ‘single’ file, file size, file format, file content, etc that causes this.

It also started as of recently, but I can’t pinpoint the date

Edge’s pdf reader works perfectly fine with the same pdf files

My computer has an i7-10700 and a GTX 1660 with studio drivers, if any of that matters, although my suspicion is that it doesn’t

As a matter of fact, I’ve noticed that closing the “This appears to be a long document” banner reduces the severity of the stuttering, but does not eliminate it, so my guess is that it’s the AI crap that’s causing this

Typing this out gave me an idea, and surely enough going to “Preferences > Generative AI“ and disabling “Show Document Summary Banner in the Viewer” made the documents silky smooth again after an acrobat restart

Can we get a report on where this is? 12 days is a long time in the software world for such a glaring bug in an expensive piece of software...

@Amal Jaiswal Are there any updates on this? My users are on the same exact version and experiencing the same exact issue on every PDF they open. It looks like the video uploaded. Multiple user tickets for the same exact issue. I have uninstalled and reinstalled Acrobat and it makes no difference.

At a certain point the owner is just going to call it curtains on Adobe products at this office, this is two tickets open against the current version for us.

Here is a form that exhibits the scrolling issue. This happens on both the paid AND free versions of Acrobat. Unsure how to proceed if Adobe is unable to process government forms...

Hi @dapnepep

Thanks for sharing the PDF form. I tried to replicate the issue at my end using the form that you have shared on Win 11, and the application is working fine.

Please try updating the Acrobat application to the latest version 26.001.21745 Planned update, Jul 23, 2026 Go to Help > Check for updates and reboot the computer once and check if that works.

Hi there

Thank you for sharing the video recording. As you mentioned, this is the issue with certain types of files. Would you mind sharing a sample PDF file so we can check it at our end for further testing?

When you say “checked to be on the latest version,” what version is that? I’m assuming you’re on Windows, so go to Help > About Adobe Acrobat and get the version number.

Also, is scrolling slow with every PDF or only certain ones? Try downloading some PDFs and checking their scrolling speed.

Hello Pariah,

As mentioned in the post, it is version 2026.001.21691. If I go to Help>check for updates, it says No updates available, installed: Adobe Acrobat 64 bit 26.001.21691.

Now that I’ve tested with an even wider sample of PDFs it seems it’s not all. The 20 files I tested with before were similar in nature, form fill-able with an image on it and a few pages between 4 and 8, but now I’ve tested some other PDFs and I was able to scroll a 100mb file with 482 pages just as smooth as I remember.
The problem is that I was able to navigate those files in the past just as smooth, and the other apps I tested with have the same smoothness to them. I know for a fact that the files have not changed as I tried both the live and backup version from 2 months ago when there was no problem, and the files have not been modified since.

Let me know if I can offer any more information to help resolve this.

I don’t know what Adobe is doing with Acrobat. I mainly read and print PDF documents, I’ve been spending hours to fix Acrobat. First it freezes (on two different PC’s) when you open it, I set up compatibility mode to Win 8. When you enter it it starts to bug you to subscribe to some AI options, then I print a document and the whole program stops responding. It’s not my PC; I have a high-end PC and have no issues with other apps. Not to mention the lag when scrolling.

Adobe has to realize that a PDF really isn’t a complicated file format and people do not need an AI overpowered laggy program where you can’t even normally print and read PDF’s.

Although I’ve paid for the Creative Suite, I installed SamutraPDF as my default PDF viewer. When I’ll need to edit something, I’ll just right-click open it to Adobe. This solved all my problems and my workflow is much faster without Adobe.

Hey, really sorry for what happened to you but that’s separate from the posted question and off-topic!

Hi @Men220

Hope you are doing well and thanks for reaching out. We are sorry for the trouble you are experiencing.

Thank you for the detailed report. The key clue is this: the lag disappears in Reading Mode (Ctrl+H) and doesn't happen in other PDF viewers. That points at the new Acrobat UI's rendering pipeline rather than your hardware or the PDF itself.

Would you mind sharing a small video recording of the steps you are taking and the issue as it occurs so we can get this reviewed by our development team to further isolate the issue for the fix.
