As per the issue description mentioned above, Acrobat locks up while scrolling any pdf file , is that correct?
Please try following troubleshooting steps:
1- Try rebooting the machine once if you haven't already and check if that helps.
2- Launch Acrobat as an administrator- Run an Adobe program as administrator | Windows 7, Vista
3- Try running Acrobat in compatibility mode by locating Acrobat icon on the desktop > right click > properties > compatibility tab > check the box run this program in compatibility mode for and select Windows 7 from the drop-down options. click Apply OK and check.
4- Also, try disabling Protected View / Enhanced security by clicking Edit menu > Preferences > Security (Enhanced) > select Off under Protected View > uncheck the box next to enhanced security > click OK. Relaunch Acrobat and check.
Note: Disabling protected view/ Enhanced security is for troubleshooting purpose only, and not recommended. Please turn the feature back on after troubleshooting is complete.

I did the standard turn the computer off and on and that didn't resolve the issue. I ran Adobe as an administrator and no improvements. Next, I ran Adobe in compatibility mode with Windows 7 and again, nothing.
Regarding the Protected View when I looked at the setting, it was already set to disabled. Switched Protected View to Files from potentially unsafe locations and also tried All files - this made the scrolling worse. So leaving the setting at it's original state of Off is giving me the best performance.
I disabled the Enhanced Security and so far that has improved the performance of the scrolling in Adobe. I will let you know how that goes. Giving it a couple of days to see if it worked or not.
Note: I have not checked the Intel Graphics driver. The laptop, Toshiba Satellite S55, does not have a built in GPU. If the Enhanced Security does not fix the issue, I will look at the Intel Graphics Driver. Also, the person with this laptop will be out of town next week, so I may not respond for a little while.
So disabling Enhanced Security did a little performance improvement, but not much. Adobe is still pretty lag. I haven't checked the Intel Graphics Driver. Will look at doing that either today or tomorrow.
I applied the Intel Display Driver version 10.18.15.4281 on the laptop, Toshiba Satellite S55-C5274. So far I have seen improvements. The graphics looks much sharper. When opening and scrolling in Adobe documents, it's been much better. There has been a few times that it locked up, but not as bad.
I will test this for a few days and keep you posted on how it goes.
On the plus side, I think the graphics looks much better and clearer. However, scrolling in Adobe is still a problem. At first I thought it was fixed, but as the day went on, the locking up while scrolling pressed on.

So out of all of these, the only one that did the most help was the Protected View setting in Adobe and updating the Intel drivers. However, those still didn't really help much.
I found another article on the Adobe Forums that has helped the most. It was suggesting going into the Intel Graphics Control Panel and Setting Anti-Aliasing to "Enhance the Application Setting". After I did this, Adobe Acrobat really didn't have much of a problem with scrolling.

Acrobat still has a problem from time to time with Scrolling but it's not that bad. I was noticing when this happens, in Task Manager you will see the HDD usage between 80-100%. When Acrobat responds again, the disk usage drops down to below 30% on average. The usual time of Acrobat locking up in this case in about 3 seconds. This is a major improvement compared to before.
Guess what Adobe, as you could guess the problem is still happening. It's not as bad, but still noticeable enough to cause me to write this post. There are still PDFs that you can open and will lock up/lag when you scroll. Though, it's not as bad, but the problem is not fixed. I don't know what else to look at, any ideas Adorobat?
Sorry for the delay in the response. Shortly after I made my last post, Adobe Acrobat was updated automatically, and I was testing it to see if there were any improvements. I also tested the setting changes listed above with the new version. The update came out on October 4th, 2018 or at least that when it was applied to the employee workstation. Adobe Acrobat is currently on version 2019.008.20071 Continuous Release.
Getting the dump file is kind of hard because Adobe Acrobat only hangs for a few seconds before it starts to respond. When it hangs, it's while you are trying to zoom in/out or scroll. I have attached a dump file of an instance today where Adobe Acrobat was hanging while I was trying to zoom in/out. The document I used was a 1-page document.
