I wanted to povide a picture but have had trouble in uploading it.
If after getting a blank section on a page, I use convential `find' (Control F), that seems to eliminate all of the blanking.
Or if I mouse click on a blanked area, partial unblanking happens
Here is an example screenshot
Hi,
I am going to share with you what I do.
Your document is not just large with 400 pages, Windows 10 is also a very busy operating system running a lot of background processes. So I always recommend to disable data execution prevention (DEP) for that program or for all programs in Windows 10 (just for troubleshooting purposes).
Sometimes you will not be able to do this due to additional security layers in newer versions of Windows after Windows 7. So will also need to disable the Boot . These are my suggestions, take what works for you:
- Disbale Data Execution Prevention (DEP) for that program (Adobe Acrobat Reader) or for all programs in Windows. To disable DEP for all the system programs open the command prompt terminsl as Administrator and paste this: bcdedit.exe /set nx AlwaysOff
- To enable at a later time bcdedit.exe /set nx AlwaysOn
- If I am not able to disable it due to secure boot restrictions you need to disable secure boot following this guidance : https://docs.microsoft.com/en-us/windows-hardware/manufacture/desktop/disabling-secure-boot or by disabling it manually from your BIOS UEFI settings, like it is suggested here: https://www.thewindowsclub.com/disable-secure-boot-in-windows
- Even though you're bringing down a security layer, when you're in control of your machine you get the added benefit of being able to troubleshoot hardware the way it is intended to perform (this case (your issue) in particular involves some sort of issue on how memory addressing and memory allocation is handled between the OS, the graphic cards adapter firmware, its driver, and computer chipsets: not just the CPU ). This is what DEP really does in a Windows machine https://www.online-tech-tips.com/windows-xp/disable-turn-off-dep-windows/
- The next thing I also do is to enable all the cores of my CPU and all the threads that are usually reserved for Windows only.
- In addition, I also add Data Collector Sets for the Processor and Process items; the same I do for the graphics card. This makes all CPU cores available to all applications. See here for how to: https://www.youtube.com/watch?v=8unagKHPGt8 and here https://www.youtube.com/watch?v=0T_IHdOnc3w
- Then, in Windows Explorer, I also go here : C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroRd32.exe
- Right-click on AcroRd32.exe and change the high DPI settings for the misbehaving application as illustrated in my slide below:
I see a lot of people in the forums posting threads of having blank screens and similar issues with other Adobe Creative Cloud apps in these forums, but since I never receive feedback from some of the ones I've helped, my question is Did they even try these suggestions at all?
My point is, and not to sound too frustrated, is that the memory allocation that is handled by newer and more robust operating systems doesn't necessarily means that it will always work well nor reliably with newer apps, specially after unattended updates in the system.
Certain apps and processes get all messed up during an unattended update at any moment. And the user never has control over that unless he/she are a high-speed IT manager who really read and check every crash dump, logs, and analyze memory dumps 24/7 for a living.
I would like to hear from you a confirmation if you were able to apply all or some of the suggestions above to correct the issue and actually see some improvement. It would give me peace of mind to know that this approach helps so I can continue to share it with others more confidently..
Last, you can always re-check with the Reader application opened, in Edit--->>>Preferences and tweak other settings in Accessibility, Page Display, 2D Rendering, hardware acceleration, using system theme modes, etc.
