Big Sur - Preview issues when viewing pdf's

Greetings Michele8991!

We see you are having some trouble with PDF files switching between multiple items when scrolling through a PDF. We can absolutely see how that would be confusing and we want to help take a look. To start, try testing this issue in safe mode to see if it is related to any user settings: How to use safe mode on your Mac. Also does this issue occur with all PDF files or just specific ones? Are you using an external mouse or the one that came with your device?

Have a great rest of your day!

Same here. it happened when i updated my Imac to big sur 11.2.2 (and 11.2.3 haven't fix it).

1. i can't use pdf full-screen anymore: if i open 2 pdf (one full-screen) i can't scroll and use the one on the desktop: after few sec it has effect on the full-screen pdf!!
2. if i use 2 pdf full-screen preview will jump every 5-10s from one to another; it become unusable
3. Microsoft word double every page of some files (example: if my docx file had 2 pages, now it has 4)

I am experiencing the same issues. Indeed, the issue does not seem to be related to any particular PDF. Restarting does not help. Would be great if this could be resolved soon, as Preview is practically unusable in fullscreen like this.

A temporary workaround is to open a new desktop, and open the preview window there. This, however, is far from ideal.

This same thing is happening to me and I even went as far as buying a new Mac because of it! I only use my Mac for Preview and for viewing/editing up to 15 files at a time and this CAN NOT continue as it majorly decreases production. How does one go about getting Apple to fix something like this?

It's most definitely a Big Sur problem. I did NOT have this issue with Catalina. I wish I hadn't upgraded until I knew for sure this issue was fixed. It's not Preview's ONLY issue, I just think it's the biggest that needs to be fixed ASAP.

I'm having the exact same issue. Since updating to Big Sur (including the most-recent update to Big Sur 11.1), my full-screen pdfs show a set up slideshow buttons at the bottom (track back, play, track forward), and after a few seconds the computer automatically will cycle to my second and third full-screen PDFs when I didn't want it to. I didn't press the play button, hoping that would avoid the problem, but it doesn't. Didn't have this problem prior to Big Sur.

I'm having the exact same problem. Studying is basically impossible with this issue, which is nonsense in the current pandemic situation.

I recorded a short video displaying the issue: https://youtu.be/MfkqWFrrhRI

How could you leave a bug like this in the OS? And it wasn't even fixed with the macOS 11.1 update!

I also have the exact same issue with my 2015 13 inch Retina MacBook Pro, The problem is so annoying, I regret why i updated to Big Sur. When 11.1 update came out I expected that the problem would be fixed but **** to the Big No. It persists. My work is terrebily affected.

I request Apple to kindly look into this issue and fix it with a quick update.

I am having the exact issue. Also, after upgrading to Big Sur, my Mac has slowed down considerably, especially when an office 365 app is open in the background. Even switching between desktops is not as smooth anymore.

I need to mention that my Mac book pro is a 16-inch 2019 with processor 2.4 GHz 8-Core Intel Core i9 and memory 64 GB 2667 MHz DDR4 which means those having the problem do not need to change their Macs! It is definitely not a hardware issue. It is a shame that Apple let this happen to the users :(

Have same exact same problem. Reported to apple befor 11.1 update-Nothing happened. Reported before 11.2 update yet again nothing happed. I am so frustrated. Im a college student who view pdfs all the time, now i feel like smashing my MacBook against the wall. Apple doesn't give a **** about the issue. In the name of updates they are making old devices more and more unusable. Latest an greatest Big Sur is nothing but a big Hoax to me.

Been hunting for solutions for the issue, have exactly the same one. Tried every thing. Reported the issue filed a feedback two times, did every thing to draw some Apple developer's attention before each-what we say the so called greatest-update but no attention to the problem has been laid on. Reported before 11.1 update, 11.1 came out the problem persist. Again reported before 11.2 update yet again noting got fixed. I feel fooled now updating to the latest and greatest Hoax Big Sur. My College work is terribly effected. I feel cheated.

i have this problem after the upgrade to macos 11.2.2 from 11.2.1. i can't use pdf in full-screen with preview: if i use 2 pdf (1 in fullscreen), preview will scroll only the full-screen one, even if i'm reading the second pdf on the desktop. WTF is going on?!

Hi DanielleM182

I waited the update of Big Sur for several times, but disappointedly, Apple still doesn't solve the problem until now. It is very inconvenient for someone who need to read papers for a long time in each day. You should tell your engineers this problem! The best description of this problem is from gymate1's video. https://youtu.be/MfkqWFrrhRI

Waiting for Apple solving the problem!

I'll jump on the bandwagon too, same problem with a 2019 MacBook Pro. I made the move from Mojave to Big Sur primarily for the Sidecar option but use Preview on a daily basis for work and this is incredibly frustrating. Even worse is seeing this thread has been around for months with no apparent fix from Apple.
