Huge annoying problem-> Mac previews "Cammand + Tab" jumps the pdf page to the very top of the page.

So lets say I have a pdf file and open it to page like 25. So when I use Mac previews and "command + tab" to switch between apps, it like changes pages from like page 25 back to page 1. Like when I "command + tab" from chrome and then back into Mac preview, it will go back I was on page 1 even though I was on like page 25. This seems to happen when I also use the 3 finger gestures or force touch sometimes.

When I switch into previews app, the app for some reason auto scrolls all the way back up to page 1. It happens often but it is random. I can sometimes switch between tabs with no issue but it happens often., What is going on here?

Another problem I am having is that sometimes I have a stick note that I start and then for some reason the expanded sticky note in the previews app won't go away. Like I can scroll through pages or do anything like add another note but the one that is stuck is stuck on top of the screen indefinitely. It will only go away if I close the app and then re-open the app. Not sure if this is a MacBook 2021 problem cause I have a new m1 MacBook Pro 16inch.

Well you can try and trouble shoot further:

—Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc., system accelerations are disabled so things will be slower & choppy—however third party system modifications are disabled as well..

Login and test. Reboot as normal and test. Caches get rebuilt automatically.

This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

—Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac

This will tell you if it a universal issue or isolated to your user/admin account.

So in safe mode it does not seem to jump pages. So how can I isolate the problem ? Any thoughts ? If I want to fix the problem do I have to reinstall Mac OS? If so is there a way that I can do it without removing all of my doc files and and pictures. I assume there is. Sorry I am a windows users. U can just tell me yes or no and I can search it up.

Yes you can reinstall the macOS on top of your existing macOS leaving your user files untouched.

Hmm well I think the problem fixed itself some how cause it is not happening at the moment when I logged back in normally. Will let you guys know if it comes up again. Thank you

This is an important part of the trouble shooting—Reboot as normal and test. Caches get rebuilt automatically

The System cache files can get corrupted.
